Chemical agents are used every day in healthcare settings throughout the United States. Dental offices rely on chemicals to disinfect contaminated surfaces, etch teeth before application of resin restorations, disinfect canals during root canal treatment, and for countless other purposes. These benefits do not come without some risks. Inappropriate handling, use, and disposal of chemicals have been responsible for injuries, illnesses, and environmental pollution. In response to concerns about exposure to hazardous chemicals in the workplace, the United States Occupational Safety and Health Administration (OSHA) issued the Hazard Communication Standard in 1983. The latest update was published in 2012. This broad regulation applies to all workplaces that have at least one employee. Because the same rule applies to industrial and professional settings, a thorough review of the regulation as it relates to the practice of dentistry is necessary. At first glance, the regulation would seem to apply to those workplaces that have large amounts of hazardous chemicals in use on a regular basis. However, the Hazard Communication Standard applies to all workplaces that have at least one employee who is exposed to potentially hazardous chemicals on the job. Additional rules for hazardous waste complete the cycle of responsibility for hazardous materials in the workplace. Material Safety Data Sheets are now known as Safety Data Sheets and will improve workers’ understanding of hazards involved. Manufacturers have until June 1, 2016, to comply.

About 43 million American workers are exposed to chemicals in the workplace. Chemical exposures may cause or contribute to many serious health conditions such as organ damage, respiratory failure, illness, cancer, burns, sterility, and dermatitis. There are more than 600,000 existing chemical products, with hundreds more entering the marketplace every year. Often employers and employees are unaware of the potential adverse effects of these chemicals. Of occupational concern is the proper usage, storage, handling, and first aid procedures associated with chemicals. In response to these issues, the Occupational Safety and Health Administration (OSHA), a division of the United States Department of Labor, issued the Hazard Communication Standard in 1983. This standard was revised in 1987 and again in 1988. In 2012, OSHA adopted major changes to align with the United Nations’ Global Harmonized System of Classification and Labeling of Chemicals. The provisions of the revisions resulting from these changes must be phased in between December 1, 2013, and June 1, 2016. The standard addresses specific issues related to chemical hazards in the workplace and gives guidelines for developing a Hazard Communication Program. However, OSHA does not dictate how the provisions of the regulation must be met. It is the responsibility of each employer to assess the hazards present in the workplace and determine the appropriate level of training and precautionary measures.

Additional regulations that relate to hazardous chemicals in the workplace exist. Most notable are the requirements for hazardous waste storage and disposal. In this article, the requirements of the Hazard Communications Standard and hazardous waste regulations, including means of compliance as they relate to the practice of dentistry, will be discussed.

Hazardous Waste And Hazardous Materials Regulations

A matrix of regulations applies to hazardous chemicals and this may create confusion for those trying to meet regulatory requirements. Briefly stated, these regulations fall into three general areas. Hazard Communication is an OSHA regulation, and as such, has provisions that are intended solely to protect the health of the working people of the United States. This regulation will be outlined in detail later in this article. Hazardous Materials Registration is required in many locations to provide emergency response personnel with access to information about chemicals that may pose a special hazard in the event of fire or other emergency. It is simply a list of all chemicals in the workplace that is submitted to the local health department upon request. The registration may also require the employer to develop a written hazard response plan and address additional issues such as proper storage and labeling of chemicals in the workplace. The third area of concern with chemicals is the storage, transportation, and disposal of chemical waste products that may pose a threat to the environment or to human health.

Hazardous Waste

The Environmental Protection Agency (EPA) regulates chemicals as they relate to the environment. A hazardous waste is a waste, or combination of wastes, which because of their quantity, concentration, or physical or chemical properties, may:

1. Cause or significantly contribute to an increase in mortality or an increase in serious irreversible illness; or

2. Pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or discarded.

A chemical discharge to the water, land, or air that may be hazardous is under the jurisdiction of the EPA. The EPA classifies hazardous chemicals into four major categories. The categories include chemicals that are flammable, corrosive, toxic, or reactive. Specific guidelines for classification of hazardous waste exist and may vary from state to state. In general, the classification definitions are as follows:


• It is not aqueous and when mixed with an equivalent weight of water, produces a solution with a pH <2 or >12.5.

• It is not a liquid and, when mixed with an equivalent weight of water, produces a liquid that corrodes steel at a rate greater than .250 inch per year at a temperature of 130ºF.


• Normally unstable and readily undergoes violent change without detonating.

• Reacts violently with water.

• Forms potentially explosive mixtures with water.

• When mixed with water, it generates toxic gases, vapors, or fumes of a quantity sufficient to present a danger to human health or the environment.

• Contains enough cyanide or sulfide to react with a pH between 2 and 12.5 and generate toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment.

• Is capable of detonation or explosive reaction if it is subjected to a strong initiating source or heated under confinement.

• It is readily capable of detonation or explosive decomposition or reaction at standard temperature or pressure.

• Is a forbidden explosive per 49 CFR Sec. 173.51, Class A explosive per 49 CFR Sec. 173.53 or Class B explosive per 40 CFR Sec. 173.88.


• A liquid other than an aqueous solution containing less than 24% alcohol with a flash point <140ºF.

• A liquid capable under standard temperature and pressure of causing a fire through friction, absorption of moisture or spontaneous chemical charges and, when ignited, burns so vigorously and persistently that it creates a hazard.

• Ignitable compressed gas.

• Oxidizer as defined in 49 CFR 173.151.


• An acute injurious effect exhibited immediately or shortly after exposure.

• A chronic injurious effect exhibited later.

It is often difficult, if not impossible, for the dental team to determine what may be a hazardous waste. Fortunately, most counties have readily available resources to assist in making these determinations. Local departments of toxic substances control or public health are commonly the local agencies responsible for the administration of hazardous waste and hazardous materials regulations. Often, the companies that offer hazardous waste disposal services are able to provide dental offices with the necessary information to comply with the hazardous waste regulations. These companies often offer additional services such as labeling of wastes, proper containers, training, and inspection.

Hazardous Waste Manifest

Manifests are required tracking documents that must be completed for every hazardous waste. The exemption is for wastes that will be recycled, such as amalgam. The manifests are provided by the hazardous waste hauler and provide the regulatory agencies with a means to calculate amounts of hazardous wastes from a single business, a specific location, or an industry. In some states, the dental office must submit a copy of the manifest to the EPA within 30 days of the date the waste was picked up. The waste hauler should not retain the copy of the manifest that is to be mailed by the generator of the waste. Some companies will offer to mail in the required copy as a service to their customers, but it is not a good practice to relinquish that responsibility.

Instructions for management of the manifest should appear on the back of the document. A copy of the manifest must be maintained and available for inspection for a minimum of 3 years. Because of “cradle to grave” laws that make every generator of hazardous waste responsible for the hazardous waste until it is destroyed, it is prudent to retain all manifests, keeping only those required for inspection accessible to the regulatory agencies. Manifests that are more than 3 years old should be boxed and stored with other important, but inactive, records. Hazardous waste regulations vary greatly from state to state and county to county. Some locations may require specific permits for any type of in-office treatment, such as silver recovery for recycling. Additionally, many locations provide exemptions for metal waste that can be recycled as scrap, including amalgam.

All hazardous waste must be labeled with the identity of the substance and the starting date for accumulation. Time limits for storage exist, and will vary depending on location. In general, small-quantity generators, such as dental offices, may store hazardous waste for up to 1 year.

Hazardous waste may not be placed with the regular trash, poured down the drain, or discharged to the environment in any manner. The local state or county toxics division of the public health department generally sets specific limits. These limits can vary greatly in different locations and may make the difference in how some products must be disposed. In some locations, the developer from x-ray processing units does not contain silver in amounts that exceed the discharge limits. In other locations, especially in counties where certain types of manufacturing take place, limits are strict enough to require that all x-ray-processing chemicals be handled as a hazardous waste.

The dental team rarely has the resources to perform a hazardous waste determination. Local regulatory agencies, and in some cases, component dental societies, are good resources for determining specific limits and requirements for a given area. Some commonly found dental products that are usually classified as regulated hazardous waste are glutaraldehyde, x-ray fixer, and scrap amalgam (unless recycled), among others (Table 1).

Overview of the Hazard Communication Standard

The Hazard Communication Standard is intended to ensure the evaluation of the hazards of all chemicals produced or imported, and the communication to employers and employees of appropriate handling and safe use of chemical products. This regulation is also called the employee “right-to-know” law. The responsibility for providing information is as follows:

Chemical manufacturers and importers: Determine the hazards of each chemical or product.

Chemical manufacturers, importers, and distributors: Communicate the hazard information and associated protective measures downstream to customers through labels and Safety Data Sheets (SDS).

Employers: Identify and list hazardous chemicals in the workplace. Obtain SDS and labels for each hazardous chemical. Develop and implement a hazard communication program including the items identified in this article.

This regulation is performance-oriented, which means that the specific methods by which to comply are not dictated by the regulatory agency. Each employer must become familiar with the requirements of the Hazard Communication Standard and ensure compliance. It is permissible for the employer to delegate certain tasks to staff members, such as maintaining a current inventory and ensuring that a SDS is available for each product. The employer cannot delegate responsibility for compliance and should maintain overall control of the program.

Written Hazard Communication Program

All employers must develop, implement, and maintain a written hazard communication program for the workplace. This written program must describe how the requirements for container labeling, SDS, and employee information and training will be met. The written program must contain a list of the hazardous chemicals in each work area, identify who is responsible for the program, outline how the criteria for labels, SDS and training will be met, and the means by which the employer will inform employees of the hazards of non-routine tasks. If there are several dentists working in one clinic or practice, they must inform other employees of hazards and protective measures. Numerous resources are available from OSHA to assist with understanding and complying with the Hazard Communication Standard. These resources may be found at www.osha.gov/dsg/hazcom/index.html.

Because it is the manufacturer’s responsibility to provide the appropriate label, dental office personnel do not need to add additional labels as items are received in the office. If a chemical product is to be removed from its original container and placed in another container for use by an employee, labeling of the secondary container is required. The one exception is if that product is intended to be used by the employee who is placing it into the secondary container during that work period (eg, placing temporary resin material into a plastic cup for use at chairside). The containers requiring that a label be applied by the dental staff would include spray bottles of disinfectant, small bottles used at chairside containing product poured from a larger container, containers of sterilant/disinfectant, x-ray processing baths and autoprocessing units, ultrasonic units, containers of gauze soaked in disinfectant, etc. A simple method of determining if a product requires a warning label is to check the original container. If there is a warning label on that container, one must also appear on the secondary container.

This information may be communicated through words or symbols (see Sidebar 1 and Figure 1). There are several ways of complying with this requirement. The easiest and least expensive is to request adhesive labels from the distributor. These are generally available for products such as spray disinfectant and x-ray processing chemicals. Products for which adhesive labels are not available may be labeled with a computer-generated or a typewritten label made and secured to the container with waterproof tape. Commercial labels such as those employing color-coding or the National Fire Protection Association hazard numbering system comply with the regulation. These tend to be more expensive and require additional training of personnel to understand the hazard codes.

Hazardous Chemical Inventory

It is important to conduct a complete inventory of the dental office to identify the hazardous materials that must be included in the Hazard Communication Program. It is best to methodically inventory all areas of each room in the office. All products that contain a hazard warning on the original label should be listed on the inventory. The name of each manufacturer should also appear on the inventory with the corresponding product. Exceptions to the rule do exist and are outlined in the following section.

Safety Data Sheets

Safety Data Sheets (SDS) are to be provided by the manufacturer, importer, or distributor for each hazardous substance (see Sidebar 2). Additionally, the manufacturer or distributor must provide updated SDS when appropriate. Employers must have a SDS for every hazardous chemical that they use, and the SDS for each product must be available to employees in the workplace. In order to determine if all needed SDS have been obtained, a list of chemicals needs to be compiled. Conducting an inventory as described above will do this. Only items that contain a hazard warning on the original label need be included on the inventory list. A sample inventory form is provided in Figure 2.

Some potentially hazardous materials are exempt from the Hazard Communication Standard and do not need to be included in the written program. The products that are exempt and may be found in a dental office include hazardous wastes (regulated by EPA), food, food additives, drugs, cosmetics, medical devices, alcoholic beverages, and consumer products, unless employee exposure is greater than exposure to an ordinary consumer. Products such as the sodium hypochlorite that is used for root canal irrigation and disinfection are subject to the regulation. Products such as abrasive cleaners that are used to clean noncontaminated surfaces in the same manner they would be used in a household are not subject to the regulation. The amount and use of the consumer product will determine whether or not it must be listed on the inventory sheet and a SDS maintained.

Once the inventory has been completed, a SDS for each item listed must be collected and provided in an accessible area for the employees using the listed products (see Sidebar 3). It is generally easiest to compile a binder with the SDS collected in alphabetical order, by common name. For very large clinics or dental practices, it may be necessary to provide separate binders for different areas. The key to determining if separate files are needed is to determine if the SDS for products being used by employees are easily accessible to those employees during their use of the products. If first aid information is needed because of accidental exposure to a hazardous substance, the employee should not have to spend time searching for the SDS binder. Placing SDS in a binder and placing it on a shelf does not comply with the Hazard Communication Standard. Employees must receive training in how to safety handle, store, and dispose of hazardous materials, and must understand the health hazards associated with each material. Employees must also know how to recognize an accidental release, perform proper cleanup procedures, and the first aid requirements in case of accidental exposure through contact, ingestion, or inhalation.

The SDS must be in English, reference the common name of the product, and contain information regarding the specific chemical identity. There are commercial programs, both written and computer software, available that provide numerous SDS with chemical generic names. This would not meet the requirements for the dental office of referencing the common name (ie, the specific brand of disinfectant used). The manufacturer or distributor must provide the SDS. If the SDS for a particular product is not provided, the employer must request it. This request should be in writing. If the requested SDS is not received with 25 working days, it is required that employers notify the local OSHA office regarding the failure of the distributor or manufacturer to comply. The manufacturer has a responsibility to prepare and supply the SDS, but it is the employer’s responsibility to ensure the information is available.

Maintaining and Updating the Inventory and SDS File

When receiving a shipment of supplies, the inventory list should be checked to ensure an SDS is on file for that product. If a new brand of product is being used, or a distributor provides an updated SDS, the new SDS should be placed in the SDS file, and the old one should be discarded. Training on proper handling, storage, personal protection, and accidental release detection is required before a new chemical product may be used. It should be clearly stated in the written Hazard Communication Program who will be responsible for maintaining the SDS file and inventory. Additionally, all training should be well documented outlining the content of the training session, who conducted the training, and who attended (see Sidebar 4 and Sidebar 5).


The Hazard Communication Program applies to all dental offices. It is possible to have a simple program, which can easily be updated as needed. The most important considerations are appointing a person who will be responsible for maintaining the inventory and ensuring employee training be conducted and documented (See Sidebar 6). Once a program is in place, annual retraining and periodic discussion at staff meetings should keep everyone up to date on the safe handling of chemical products.

Proper Labeling of Hazardous Materials
All containers of hazardous materials must be labeled before shipment. The determination of what must be on the label is the responsibility of the manufacturer, distributor, or importer. This means that all containers entering the dental office have been properly labeled and do not require additional labels to be affixed. The information that is required includes:
❑ Product identifier (may be name, code, batch, etc.)
❑ Signal word (“Danger” or “Warning”)
❑ Pictogram (Figure 1)
❑ Hazard statement
❑ Precautionary statement
❑ Name and address of the chemical manufacturer, importer, or other responsible party


Safety Data Sheets
Safety Data Sheets (SDS) are to be provided by the manufacturer, importer, or distributor for each hazardous substance. Additionally, the manufacturer or distributor must provide updated SDS when appropriate. Employers must have a SDS for every hazardous chemical that they use, and the SDS for each product must be available to employees in the workplace. In order to determine if all needed SDS have been obtained, a list of chemicals needs to be compiled. Conducting an inventory as described above will do this. Only items that contain a hazard warning on the original label need be included on the inventory list. A sample inventory form is provided in Figure 2.


Information Needed on All SDS
All SDS must contain at least the following information:
❑ Identification, including product identifier, manufacturer or distributor contact information, recommended use, restrictions on use
❑ Hazard(s) identification
❑ Composition/information on ingredients
❑ First-aid measures
❑ Fire-fighting measures
❑ Accidental release measures
❑ Handling and storage
❑ Exposure controls/personal protection
❑ Physical and chemical properties
❑ Stability and reactivity
❑ Toxicological information
❑ Ecological information
❑ Disposal considerations
❑ Transport information
❑ Regulatory information
❑ Other information


Employee Information and Training
Hazard communication training must be provided to employees who may be exposed to hazardous chemicals in the workplace. In addition, training of all employees of the requirements adopted in 2012 must take place by December 1, 2013. This training must be provided at the time of initial assignment whenever a new hazard is introduced into the workplace, or if the employee is reassigned.
There are minimum requirements for employee information and training that must be met. At a minimum, the discussion topics must include:
❑ The existence of the hazard communication standard and the requirements of the standard
❑ The components of the individual hazard communication program
❑ Operations in work areas where hazardous chemicals are present
❑ Where the employer will keep the written hazard evaluation procedures, written program, and SDS forms


Formal Training Program Requirements
A formal training program is required. A summary of the training contents should be provided along with a list of employees attending the training session, the name of the person conducting the training, and the date of the training. These records should be kept for a minimum of 3 years. OSHA has identified the minimum requirements for the content of a hazard communication training program as follows:
❑ How the hazard communication program is implemented in the office, how to read and interpret information on the SDS, how employees can obtain and use available hazard information
❑ The hazards of chemicals in the work area
❑ Protective measures to prevent exposure
❑ Specific procedures to provide protection such as personal protective equipment, and work practice and engineering controls
❑ How to detect the presence of a hazardous chemical (smell, appearance, etc.)


Self-Evaluation for Compliance Self-evaluation is an important tool in ensuring compliance. The following checklist will help to ensure compliance with the regulation.
❑ Obtained a copy of the rule
❑ Read and understood the requirements
❑ Assigned responsibility for tasks
❑ Prepared an inventory of chemicals
❑ Ensured containers are labeled
❑ Obtained SDS for each chemical
❑ Prepared written program
❑ Made SDS available to employees
❑ Conducted training of workers
❑ Established procedures to maintain current program
❑ Established procedures to evaluate effectiveness
