2024

• What is the primary goal of the Global Harmonized System (GHS)?
• To ensure safe and secure transportation of hazardous materials
• To promote common criteria for classifying chemicals according to

their health, physical, and environmental hazards

• To provide a universal system of color coding for chemical

containers

• To regulate the international trade of chemicals

Answer: B) To promote common criteria for classifying chemicals

according to their health, physical, and environmental hazards

Rationale: The GHS aims to standardize and harmonize the

classification and labeling of chemicals to enhance the protection of human health and the environment by providing an internationally comprehensible system.

• In the context of GHS, what does the term "hazard communication"

refer to?

• The process of transporting hazardous materials from one location to

another

• The methods used to warn individuals about areas where hazardous

materials are stored

• The exchange of information about hazards and protective measures

between manufacturers and users of hazardous products

• The signage used to indicate the presence of hazardous materials in a

facility

Answer: C) The exchange of information about hazards and protective

measures between manufacturers and users of hazardous products

Rationale: Hazard communication is a critical component of GHS,

which ensures that the information about the chemical hazards and associated protective measures is conveyed to the end-users.

• Which of the following is NOT a direct benefit of implementing GHS?
• Reduction in the incidence of chemical-related occupational diseases

and injuries

• Enhanced corporate image and credibility
• Increased cost of training due to the complexity of the system
• Improved efficiency in hazard communication

Answer: C) Increased cost of training due to the complexity of the

system

Rationale: While GHS may initially require investment in training, the

overall goal is to reduce costs by providing a consistent framework for hazard communication, thus C is not a direct benefit but a potential initial challenge.

• What is the significance of Safety Data Sheets (SDS) in GHS?
• They provide instructions for the safe handling of food products
• They contain detailed information about the properties of a particular

substance or mixture

• They are used to track inventory levels of chemicals in a warehouse
• They serve as a logbook for recording accidents involving chemicals

Answer: B) They contain detailed information about the properties of a

particular substance or mixture

Rationale: SDS are essential in GHS as they provide comprehensive

information about the substance or mixture for use in workplace chemical management and by emergency personnel.

• Under GHS, which pictogram is used to denote a substance that is an

oxidizer?

• Flame
• Flame over circle
• Exclamation mark
• Gas cylinder

Answer: B) Flame over circle

Rationale: The flame over circle pictogram is used for oxidizing

substances under GHS, as these materials may cause or intensify a fire.

• What does the GHS hazard statement "Highly flammable liquid and

vapor" imply about a substance?

• It has a low flash point and can catch fire easily at normal

temperatures

• It is only flammable when in a gaseous state
• It is safe to store near heat sources
• It requires a special type of fire extinguisher to be put out

Answer: A) It has a low flash point and can catch fire easily at normal

temperatures

Rationale: This hazard statement indicates that the substance has a low

flash point and can easily ignite, which requires careful handling and

storage away from ignition sources.

• In the GHS labeling system, what information is provided by the signal

word?

• The chemical name and formula of the substance
• The level of severity of the hazard posed by the chemical
• The antidote for exposure to the chemical
• The date the chemical was manufactured

Answer: B) The level of severity of the hazard posed by the chemical

Rationale: The signal word on GHS labels indicates the severity of the

hazard, with "Danger" for more severe hazards and "Warning" for less severe hazards.

• Which GHS precautionary statement would be appropriate for a

chemical that can cause skin irritation?

• "Do not breathe dust/fume/gas/mist/vapors/spray"
• "Wash skin thoroughly after handling"
• "Keep away from heat/sparks/open flames/hot surfaces - No

smoking"

• "Use only outdoors or in a well-ventilated area"

Answer: B) "Wash skin thoroughly after handling"

Rationale: This precautionary statement is relevant as it advises on

immediate action to reduce the risk of skin irritation from chemical exposure.

• How does GHS contribute to the cleaning, maintenance, and restoration

industries specifically?

• By providing aesthetic guidelines for product packaging
• By ensuring that workers are informed about the hazards of

chemicals they may encounter

• By regulating the prices of cleaning chemicals
• By mandating the use of specific cleaning techniques

Answer: B) By ensuring that workers are informed about the hazards of

chemicals they may encounter

Rationale: GHS enhances worker safety in these industries by ensuring

that employees are well-informed about the chemical hazards and can take appropriate precautions.
