FREE STSC Hazard Communication (HazCom) and Chemical Safety Questions and Answers

Question 1

As a construction supervisor, what is your primary responsibility regarding Safety Data Sheets (SDSs) on the job site?

Accepted Answer

Ensuring SDSs are readily accessible to all employees for every hazardous chemical on site.

Answer

The OSHA Hazard Communication Standard requires employers to maintain copies of SDSs for each hazardous chemical and ensure they are readily accessible during each work shift to employees. The supervisor is responsible for implementing this on site, ensuring workers can quickly find information in an emergency.

Question 2

A container of a chemical on your construction site displays a GHS pictogram showing a flame over a circle. What type of hazard does this indicate?

Accepted Answer

Oxidizer

Answer

The 'flame over circle' pictogram specifically represents an oxidizing hazard. Oxidizers can cause or contribute to the combustion of other materials, usually by yielding oxygen, and pose a significant fire or explosion risk, separate from being merely flammable.

Question 3

Which of the following is a mandatory component of an employer's written Hazard Communication program?

Accepted Answer

A list of hazardous chemicals on site and the methods used to inform employees of hazards.

Answer

A written HazCom program must include a list of the hazardous chemicals known to be present, the methods the employer will use to inform employees of the hazards (e.g., labels, SDSs, training), and procedures for non-routine tasks. This inventory is a core requirement for managing chemical hazards effectively.

Question 4

An employee transfers a cleaning solvent from a large manufacturer's drum into a smaller, portable spray bottle for use during their shift. What must the supervisor ensure is done with the spray bottle?

Accepted Answer

It must be labeled with the product identifier and words, pictures, or symbols that provide hazard information.

Answer

OSHA requires that secondary containers, like the spray bottle, be labeled with either a copy of the original manufacturer's label or a workplace-specific label. This workplace label must include the product identifier and words, pictures, or symbols that provide general information about the chemical's hazards.

Question 5

According to the OSHA Hazard Communication Standard, when must an employee receive initial training on hazardous chemicals?

Accepted Answer

At the time of their initial assignment and before working with a new chemical hazard.

Answer

HazCom training is required before an employee begins work with hazardous chemicals and whenever a new chemical hazard is introduced into their work area. The goal is to ensure workers have the information they need to protect themselves *before* exposure can occur.
