Chemical Hazards Control

Which control measure involves replacing a hazardous chemical with a less hazardous one?

• PPE

• Isolation

• Elimination

• Substitution

What is the purpose of isolation in chemical hazard control?

• To eliminate the chemical entirely

• To separate hazardous chemicals from people

• To substitute with a safer chemical

• To provide personal protective equipment

Which of the following is an example of an engineering control?

• Housekeeping

• Modified work scheduling

• Local exhaust ventilation

• Chemical safety policies

What is the main goal of administrative controls?

• To eliminate hazardous chemicals

• To reduce exposure frequency and severity

• To provide personal protective equipment

• To isolate hazardous chemicals

What is the primary focus of the hierarchy of controls?

• To eliminate all chemicals

• To reduce harm and risk of illness

• To enhance worker productivity

• To increase chemical production

What is an example of a situation where elimination of a chemical is most effective?

• Using a less hazardous chemical

• Banning a toxic chemical

• Isolating a chemical in a cabinet

• Using PPE

Which control measure is considered the last resort in the hierarchy?

• Engineering control

• Isolation

• Substitution

• PPE

Which of the following is a limitation of PPE?

• It is always effective

• It is the first line of defense

• It requires adherence to rules

• It eliminates the hazard

What type of ventilation is used to dilute contaminants in a work environment?

• Mechanical ventilation

• Containment

• Natural ventilation

• Local exhaust ventilation

What is the role of local exhaust ventilation?

• To eliminate the need for PPE

• To provide fresh air

• To capture contaminants at the source

• To dilute contaminants
