Minimizing Risks in Chemistry: NIOSH Hierarchy of Controls

The video tutorial covers the importance of personal protective equipment (PPE) and the RAMP process for minimizing risks in a lab setting. It explains the four main routes of chemical exposure: inhalation, skin contact, ingestion, and injection. The hierarchy of controls is introduced as a method to reduce risk, with a focus on engineering and administrative controls. The video also emphasizes the correct use of PPE, including eye protection, gloves, and lab coats, and discusses acceptable risk levels in labs. Finally, it highlights the importance of constant vigilance to ensure safety.

What does RAMP stand for in the context of lab safety?

• Recognize, Assess, Manage, Prevent

• Recognize, Avoid, Manage, Prepare

• Recognize, Avoid, Minimize, Prevent

• Recognize, Assess, Minimize, Prepare

Which is the most common route of chemical exposure in the lab?

• Injection

• Inhalation

• Ingestion

• Direct contact with skin

What is a less common route of chemical exposure in the lab?

• Inhalation

• Direct contact with skin

• Ingestion

• Injection

What is the best way to minimize risk according to the hierarchy of controls?

• Substitution

• Engineering controls

• Administrative controls

• Elimination

What is the primary purpose of a fume hood in the lab?

• To contain fires

• To remove gases and vapors

• To store chemicals

• To provide lighting

What should you check to ensure a fume hood is working properly?

• The temperature inside the hood

• The size of the hood

• The test sticker and airflow

• The color of the hood

What type of eye protection is generally required in chemistry labs?

• Safety glasses

• Indirectly vented splash goggles

• Face shield

• Regular glasses

Why is it important to wear long sleeves in the lab?

• To follow fashion trends

• To stay warm

• To minimize skin exposure

• To look professional

What should you do with lab gloves after using them?

• Reuse them for the next experiment

• Wash and dry them

• Store them in your locker

• Discard them as directed by your instructor

Why is it important to remove gloves correctly?

• To avoid tearing them

• To prevent chemicals from contacting your skin

• To save time

• To look professional
