Summary
âś OSHAâs HazardCommunication Standard is based on a
simple concept - that employees have both a need and a
right to know the hazards and identities of the chemicals
they are exposed to when working
âś Employees also need to know what protective measures
are available to prevent adverse effects from occurring.
âś Reporting injury or incident is protected by law
âś Disciplinary action against employee for reporting an
injury or incident is in violation of OSH Act

This PowerPoint is designed to focus on chemical safety and hazards identification. It briefly covers the hierarchy of hazard controls and OSHAâs Right to Know law. The main goal of this training initiative is to create safer work practices and a safer work environment in order to prevent workplace illnesses and injuries.
#4Â 1 OSHA 3084; Chemical Hazard Communication. https://www.osha.gov/Publications/osha3084.html
Revised in 1998. We expect both the number of workers and the number of chemicals has increased since then.
This is one of the most frequently cited OSHA standards.
This program is intended for workplaces that do not manufacture, import, or distribute hazardous chemicals. Notes have been provided that highlight some of the requirements for these employers. For complete requirements, consult 29 CFR 1910.1200.
#6Â There are 4 main ways a chemical can enter the body:
Inhalation: For most chemicals in the form of vapors, gases, mists, or particulates, inhalation is the major route of entry. Once inhaled, chemicals are either exhaled or deposited in the respiratory tract. If deposited, damage can occur through direct contact with tissue or the chemical may diffuse into the blood through the lung-blood interface.
Upon contact with tissue in the upper respiratory tract or lungs, chemicals may cause health effects ranging from simple irritation to severe tissue destruction. Substances absorbed into the blood are circulated and distributed to organs that have an affinity for that particular chemical. Health effects can then occur in the organs, which are sensitive to the toxicant.
⢠Skin (or eye) absorption: Skin (dermal) contact can cause effects that are relatively mild such as redness or irritation (dermatitis); more severe effects include destruction of skin tissue or other debilitating conditions. Many chemicals can also cross the skin barrier and be absorbed into the blood system. Once absorbed, they may produce systemic damage to internal organs. The eyes are particularly sensitive to chemicals. Even a short exposure can cause severe effects to the eyes or the substance can be absorbed through the eyes and be transported to other parts of the body causing harmful effects.
⢠Ingestion: Chemicals that inadvertently get into the mouth and are swallowed do not generally harm the gastrointestinal tract itself unless they are irritating or corrosive. Chemicals that are insoluble in the fluids of the gastrointestinal tract (stomach, small, and large intestines) are generally excreted. Others that are soluble are absorbed through the lining of the gastrointestinal tract. They are then transported by the blood to internal organs where they can cause damage.
⢠Injection: Substances may enter the body if the skin is penetrated or punctured by contaminated objects. Effects can then occur as the substance is circulated in the blood and deposited in the target organs.
#8Â Neurologic symptoms can include:
muscle weakness,
partial or complete loss of sensation,
partial or complete paralysis,
seizures,
loss of cognitive abilities,
unexplained pain
decreased alertness
Respiratory symptoms can include:
sore throat
coughing/wheezing
shortness of breath
decreased lung capacity/decreased lung function
suffocation/asphyxiation
lung cancer
Respiratory symptoms can include:
heart failure
inability of blood to carry oxygen throughout the body
#9Â Immunologic symptoms can include:
allergy
immune system slow down or failure
autoimmune disorders (body attacks itself)
Mutagens can cause a permanent change to the DNA, which may harm cells and cause certain diseases (such as cancer).
Mutations can be passed down to offspring
Teratogens can affect the development of an embryo or fetus, which may cause birth defects
Carcinogens can affect the DNA directly (similar to mutagens), but can also cause cells to divide at a faster rate, which could increase the likelihood of cell division error, which could result in changes to the DNA code (mutation)
#10Â biological - bacteria, viruses, insects, plants, birds, animals, and humans, etc.,
chemical - depends on the physical, chemical and toxic properties of the chemical,
ergonomic - repetitive movements, improper set up of workstation, etc.,
physical - radiation, magnetic fields, pressure extremes (high pressure or vacuum), noise, etc.,
psychosocial - stress, violence, etc.,
safety - slipping/tripping hazards, inappropriate machine guarding, equipment malfunctions or breakdowns.
#11 Flammable: Material that will burn or ignite, causing fire or combustion. An ignitable chemical has a flashpoint less than 100° F. A combustible material will burn, but require a flame or elevated temperature plus a spark to start them; and has a flashpoint greater than 100° F but less than 200° F.
Corrosive: Chemical that causes visible destruction of, or irreversible alterations in, living tissue by chemical action at the site of contact.pH < 2 and pH > 12.5
Reactive: Material that reacts violently or explodes under either ambient conditions or when in contact with air, water, or other chemicals.
Oxidizers: materials that react strongly with organic materials, sometimes strongly enough to start fires
#12Â Organic Peroxides: form friction and shock-sensitive explosives
Water Reactive: react violently with water
Air Reactive (pyrophoric): react violently with air
#13Â Toxic: Material that may cause harm to an individual if it enters the body.
Carcinogen: a substance or agent that may cause cancer
*IARC classifies formaldehyde as a human carcinogen; EPA classifies it as a probable human carcinogen
Mutagen: An agent that can induce or increase the frequency of mutation in an organism
Poison: any substance that can impair function, cause structural damage, or otherwise injure the body
#14Â Sensitizer: a substance that causes hypersensitivity or reactivity to an antigen, such as pollen, especially by a second or repeated exposure.
Teratogen: An agent that causes malformation of an embryo or fetus.
Irritant: Material that can cause harm to an individual in the following ways:
Irritant: a substance that can irritate the skin or eyes
Skin Sensitizer: a substance which can cause an allergic response following skin contact
Acute Toxicity (harmful): a substance that may be fatal or cause organ damage from a single short-term exposure
#16Â Eliminating the hazard is the most effective method of controlling hazards. Next best is substituting the hazard for a non- or less hazardous chemical or process. However, for existing operations, elimination and substitution may be the most difficult to implement, as major changes may be needed to remove the hazardous substance or process.
Engineering controls are designed to remove the hazard at the source, before it comes in contact with the worker. This is preferable to administrative controls or personal protective equipment (PPE) because it is not dependent on human action or behavior. The initial cost of engineering controls can be higher than the cost of administrative controls or PPE, but may lower operating costs in the long term.
Administrative Controls are aimed at changing the human element of the work process or schedule. For example, limiting an employeeâs time in an area of exposure, rotating shifts, etc.
PPE is safety equipment worn by the employees to protect them from the hazard(s) they come into contact with. Administrative controls and PPE rely heavily on the employees for implementation.
Administrative controls and PPE have been demonstrated to be less effective than other measures. They may be relatively inexpensive to establish (particularly when compared to the up-front cost of an engineering control) but, over the long term, can be very costly to sustain (eg, continuously purchasing PPE).
#17Â Chemical manufacturers and importers must review scientific evidence on the hazards of chemicals they produce or import and report findings to their employees and to employers who distribute or use their products.
#19Â It is the employerâs responsibility to obtain Safety Data Sheets (SDSs) and labels for each hazardous chemical if they are not provided by the manufacturer, importer, or distributor
Written HazCom program includes labels, SDSs, and employee training
Communicate hazard information to employees through labels, SDSs, and formal training programs. Employees should know where to find information on hazards, and it should be accessible to them.
#20Â 1910.1200(h)
Training is not satisfied solely by giving the employee the data sheets to read. An employer's training program is to be a forum for explaining to employees not only the hazards of the chemicals in their work area, but also how to use the information generated in the hazard communication program. This can be accomplished in many ways (audiovisuals, classroom instruction, interactive video), and should include an opportunity for employees to ask questions to ensure that they understand the information presented to them. Training must be carried out in a language that is comprehensible to the employees.
Training need not be conducted on each specific chemical found in the workplace, but may be conducted by categories of hazard (e.g., carcinogens, sensitizers, acutely toxic agents, irritants, flammables) that are or may be encountered by an employee during the course of his duties.
Employees who have been previously trained by another employer, union, or other entity, do not have to be retrained if the previous training is sufficient to meet the standardâs training requirements for the current work being performed. However, employees must have information about where to find SDSs in the workplace, who in the company is responsible for the HazCom program, and where to get copies.
#24Â It is the employerâs responsibility to obtain Safety Data Sheets (SDSs) and labels for each hazardous chemical if they are not provided by the manufacturer, importer, or distributor
Written HazCom program includes labels, SDSs, and employee training
Communicate hazard information to employees through labels, SDSs, and formal training programs. Employees should know where to find information on hazards, and it should be accessible to them.
#26Â 29 CFR 1910.1200
The Hazard Communication (HazCom) standard establishes uniform requirements to make sure that the hazards of all chemicals imported into, produced, or used in U.S. workplaces are evaluated, and that this hazard information is transmitted to affected employers and exposed employees.
The HazCom standard is different from other OSHA health rules because it covers all hazardous chemicals. The rule also incorporates a âdownstream flow of information,â which means that producers of chemicals have the primary responsibility for generating and disseminating information, whereas users of chemicals must obtain the information and transmit it to their employees.
#27Â 1910.1200(b)
Does the standard apply to an office environment?
Office workers who encounter hazardous chemicals only in isolated instances are not covered by the rule. OSHA considers most office products (such as pens, pencils, adhesive tape) to be exempt under the provisions of the rule. OSHA has stated that intermittent or occasional use of a copying machine does not result in coverage under the rule. However, if an employee handles the chemicals to service the machine, or operates it for long periods of time, then the standard would apply.
âHazardous Chemicalâ is any chemical which is a physical or health hazard.
#29Â Employer also required to describe how they will inform employees of the hazards of non-routine tasks (for example, cleaning reactor vessels), and the hazards associated with chemicals in unlabeled pipes.
#30Â 1910.1200(f)
Chemical manufacturers and importers must convey the hazard information to downstream employers by means of labels on containers and Safety Data Sheets (SDSs)
Chemical manufacturers, importers, and distributors must be sure that containers of hazardous chemicals leaving the workplace are labeled, tagged, or marked with the appropriate information. Consumer products having labels meeting requirements of the Consumer Product Safety Act do not have to have additional labeling under the HazCom Standard.
Various other chemical products (for example, pesticides, foods, drugs, cosmetics, beverage alcohols) that are subject to labeling laws administered by other Federal agencies are also exempt from the labeling requirements of the HazCom Standard.
1- Signal Word â The signal word indicates hazard level. "Danger" is used for the most severe instances, while "Warning" is less severe.
2- GHS Symbol (Pictogram)- These pictograms are used to identify hazardous products and are commonly grouped by chemical/physical risk, health risk and environmental risk
3- Manufacturer Information- This identifies the manufacturer's company name, address and telephone number.
4- Precautionary Statements/First Aid- These are phrases that are tied to each hazard statement. They describe general preventative, response, storage, or disposal precautions. These statements are found on the chemical's Safety Data Sheet. Similar to Hazard Statements, Precautionary Statements can be identified by a P-Code (like P100).
5- Hazard Statements- These are phrases that describe the nature of hazardous products and the degree of hazard. Hazard statements are on the chemical's Safety Data Sheet (SDS) and identified by an H-Code (like H100).
6- Product Name or Identifiers- This identifies the product or chemical name. Additional identifiers can be noted to the right of the Manufacturer's information (#1).
#33Â 1910.1200(g)
Chemical manufacturers and importers must develop an SDS for each hazardous chemical they produce or import, and must provide the SDS at the time of the initial shipment to a downstream distributor or user. Distributors also must ensure that downstream employers are similarly provided an SDS.
Employers who become newly aware of âany significant informationâ regarding the hazards of a chemical must revise the labels for the chemical within six months of becoming aware of the new information and labels on containers of hazardous chemicals after that time must contain the new information.
OSHA does not require that SDSs be provided to purchasers of household consumer products (such as "windex" and "whiteâoutâ) when the products are used in the workplace in the same manner that a consumer would use them, i.e.; where the duration and frequency of use (and therefore exposure) is not greater than what the typical consumer would experience. Employees who are required to work with hazardous chemicals in a greater duration and frequency of exposure than a normal consumer have a right to know about the properties of those hazardous chemicals.
#34Â In the absence of other employee exposure records, SDSs that indicate a health hazard are considered employee exposure records under the Access to Employee Medical Records standard, 29 CFR 1910.1020 and must be preserved and maintained for at least thirty years, with some exceptions.
[See 29 CFR 1910.1020(d)]
Electronic access is acceptable provided:
- A back-up procedure is available if the electronic system fails
- It can be accessed in the employeeâs work area
The telephone number provided must be that of a person who can provide additional information about the hazardous chemical and appropriate emergency procedures.
