What is the primary purpose of OSHA's Hazard Communication Standard?
To ensure that information about chemical hazards and associated protective measures is available and understandable to workers
To standardize medical treatment procedures for chemical injuries
To limit the production of hazardous chemicals by manufacturers
To regulate emissions of chemicals into the environment
The Hazard Communication Standard (HCS) aims to ensure that hazard information is available to workers. It requires chemical manufacturers, distributors, and employers to communicate hazards via labels, Safety Data Sheets (SDS), and training. This is often called the "Right-to-Know" standard.
Which section of a Safety Data Sheet (SDS) provides information on first-aid measures?
Section 2: Hazard identification
Section 14: Transport information
Section 8: Exposure controls/personal protection
Section 4: First-aid measures
GHS-aligned Safety Data Sheets are organized into 16 sections. Section 4 specifically outlines first-aid measures for different routes of exposure. It includes details on immediate treatment and recommendations for medical attention.
How many pictograms are specified under the Globally Harmonized System (GHS) for hazard communication?
8
7
9
5
The Globally Harmonized System (GHS) uses nine standardized pictograms to communicate hazards. Each pictogram represents a specific hazard class. Employers must use these pictograms on labels under the HCS.
What does GHS stand for in chemical hazard communication?
Globally Harmonized System of Classification and Labeling of Chemicals
Global Hazard Specification
General Hazard Standards
Guideline for Hazard Safety
The GHS abbreviation stands for the Globally Harmonized System of Classification and Labeling of Chemicals. It was developed by the United Nations to standardize chemical hazard communication worldwide. OSHA adopted GHS in its HCS in 2012.
Which signal word indicates the more severe hazard category under the HCS?
Danger
Caution
Notice
Warning
OSHA's HazCom standard uses two signal words: 'Danger' for more severe hazards and 'Warning' for less severe hazards. Only one signal word appears on a label, reflecting the highest severity hazard. Signal words are a quick indicator of hazard severity.
Which of the following is an example of a hazard statement under GHS?
May be harmful if swallowed
Wear protective gloves and eye protection
Keep container tightly closed
Causes severe skin burns and eye damage
Hazard statements describe the nature and degree of the hazard of a chemical. They are standardized phrases such as 'Causes severe skin burns and eye damage.' Precautionary statements, in contrast, advise on measures to minimize or prevent adverse effects.
When must employers provide hazard communication training to employees?
Training is not required under HCS
At initial assignment and whenever a new chemical hazard is introduced
Only after any chemical spill occurs
Only at the end of each calendar year
Employers must train workers on chemical hazards before initial work assignment and whenever a new hazard is introduced. This ensures employees understand label elements and SDS content. Adequate training must also cover protective measures and emergency procedures.
Under the HazCom Standard, within what timeframe must manufacturers or importers update an SDS after they become aware of significant new hazard information?
6 months
30 days
1 year
90 days
OSHA requires manufacturers and importers to update Safety Data Sheets within 90 days after becoming aware of significant new hazard information. This timeframe ensures that downstream users have current hazard information. Employers must then distribute the updated SDSs to all affected employees.
Which section of the SDS provides information on chemical stability and reactivity?
Section 12: Ecological information
Section 6: Accidental release measures
Section 3: Composition/information on ingredients
Section 10: Stability and reactivity
Section 10 of the SDS outlines chemical stability, possible hazardous reactions, conditions to avoid, and incompatible materials. This information helps users understand potential risks during storage and handling. It also notes any polymerization hazards.
At what minimum concentration threshold must hazardous ingredients generally be disclosed on the SDS under HCS?
Greater than 10%
Greater than 0.1%
Greater than 5%
Greater than 1%
Under HCS, hazardous chemicals must be disclosed on the SDS if they are present above 1% (0.1% for carcinogens, reproductive toxins, and respiratory sensitizers). This ensures that even low concentrations of high-risk substances are reported. Employers use this information for proper labeling and risk management.
Which of the following is NOT required on a GHS-compliant chemical label under OSHA's HCS?
Signal word
Hazard pictograms
Product identifier
NFPA 704 diamond (fire-health-instability ratings)
The Hazard Communication Standard mandates product identifier, signal word, hazard statement, precautionary statements, and pictograms. NFPA ratings are optional and not required on GHS-compliant labels. The NFPA diamond is a separate labeling system.
Under HCS, which of the following is classified as a physical hazard rather than a health hazard?
Carcinogenicity
Flammable liquid
Reproductive toxicity
Respiratory sensitizer
OSHA HCS classifies hazards into physical and health categories. Flammable liquids, oxidizers, and explosives fall under physical hazards. Health hazards include carcinogenicity, respiratory sensitization, and reproductive toxicity.
Which section of the SDS covers exposure controls and personal protective equipment (PPE)?
Section 16: Other information
Section 5: Fire-fighting measures
Section 11: Toxicological information
Section 8: Exposure controls/personal protection
Section 8 of the SDS details exposure controls and personal protective equipment. It lists recommended engineering controls, administrative controls, and specific PPE needed to minimize exposure. Users refer to this section to select gloves, goggles, or respirators.
Which pictogram must appear on the label for a substance that causes skin corrosion?
Flame pictogram
Corrosion pictogram (test tubes pouring on hand and metal)
Skull and crossbones pictogram
Exclamation mark pictogram
The corrosion pictogram (test tubes pouring on hand and metal) indicates skin corrosion, eye damage, or metal corrosion hazards. It alerts users to risks of chemical burns. Under HCS, this pictogram is mandatory for such hazards.
When transferring a hazardous chemical into a secondary container for immediate use by the person who performed the transfer, which labeling requirement applies?
Signal word and pictogram only
A full GHS label must be applied before any use
Product identifier only
No label is required if the chemical is under the immediate use exemption
The 'immediate use' exemption allows an employee transferring a chemical into a secondary container for use during the same shift to leave it unlabeled, provided the workplace has a labeling program and the chemical is not left unattended. This provision streamlines short-term operations without compromising safety.
According to GHS acute toxicity categories, which category represents the most severe hazard?
Category 3
Category 2
Category 1
Category 4
GHS acute toxicity is divided into Category 1 (most severe) through Category 5 (least severe). Category labels are based on lethal dose/exposure data. Employers must use the category to select correct hazard statements and pictograms.
Which GHS pictogram indicates hazards to the aquatic environment?
Flame pictogram
Health hazard pictogram (silhouette and star)
Environment pictogram (dead tree and fish)
Gas cylinder pictogram
The aquatic toxicity pictogram (dead tree and fish) denotes hazards to aquatic environments. It is mandated for chemicals classified as aquatic acute or chronic hazards. This pictogram has broad use for protecting marine and freshwater ecosystems.
Which section of the SDS provides guidance on disposal considerations?
Section 13: Disposal considerations
Section 12: Ecological information
Section 16: Other information
Section 7: Handling and storage
Section 13 of a Safety Data Sheet covers disposal considerations, including recommended disposal methods, container handling, and special precautions. Proper disposal ensures compliance with waste regulations and minimizes environmental impact.
Which pictogram must appear on the label of a chemical designated as a skin sensitizer Category 1?
Flame pictogram
Corrosion pictogram
Skull and crossbones pictogram
Exclamation mark pictogram
Skin sensitizers Category 1 require the exclamation mark pictogram under GHS. This symbol signifies less severe health hazards such as skin irritation, sensitization, and acute toxicity Category 4. It alerts users to potential allergic skin reactions.
How often should an employer internally review SDSs to ensure they remain current, even if no new information has been provided by the supplier?
Only when a new shipment arrives
At least every 3 years
Every 5 years
Every 6 months
Although manufacturers update SDSs when new hazard data emerges, employers should internally review all SDSs at least every three years to ensure they remain current. This periodic review helps maintain accurate hazard communication.
Which of the following is NOT covered by OSHA's Hazard Communication Standard?
Germ cell mutagens
Acute toxicity chemicals
Compressed gases
Radioactive materials
The Hazard Communication Standard applies to chemical hazards only. Radioactive materials are regulated separately under other OSHA and NRC standards. Compressed gases, germ cell mutagens, and acute toxicity chemicals fall under HCS requirements.
Which of the following is classified as a health hazard under the Hazard Communication Standard?
Explosive
Flammable liquid
Oxidizer
Respiratory sensitizer
Under HCS, health hazard classes include carcinogenicity, respiratory sensitizer, germ cell mutagenicity, and reproductive toxicity. Physical hazards like oxidizers or flammable liquids are separate categories. Respiratory sensitizers can cause asthma or other breathing difficulties.
According to the GHS bridging principles, if a mixture contains acutely toxic components classified as Category 3 and Category 4, what acute toxicity category should the mixture be assigned?
Category 4
Category 3
Category 2
Category 5
Bridging principles allow assigning a hazard category to a mixture based on component classification and concentration. When a mixture contains acute toxicity Category 3 and 4 ingredients but no Category 1 or 2, and ingredient concentration thresholds are met, the mixture is classified as Category 3. This approach simplifies mixture classification without additional testing.
Under OSHA's Hazard Communication Standard, which definition correctly distinguishes an importer from a distributor?
An importer is always the end-user; a distributor is always the retailer
An importer only handles nonhazardous substances; a distributor handles hazardous ones
An importer is a business that brings hazardous chemicals into the U.S.; a distributor resells those chemicals domestically
An importer manufactures chemicals; a distributor imports them
Under HCS, an importer is a business that brings hazardous chemicals into the United States. Distributors receive already imported chemicals and supply them downstream. Importers have specific responsibilities such as hazard classification and SDS development for U.S. shipments.
