This must be worn by both drivers and all passengers in a vehicle.
What are seat belts?
This is the permissible exposure limit for benzene over an 8-hour time-weighted average.
What is 0.5 ppm?
These types of filters must be used in vacuums or respirators to capture lead dust.
What are HEPA filters?
This is the initial process in oil refining that separates crude oil into different components based on their boiling points.
What is distillation?
Entry into a confined space is prohibited if the oxygen content is less than this percentage.

This document contains information on the hazards and safe handling of lead materials.
What is a Safety Data Sheet (SDS)?
This unit operation cracks larger hydrocarbons molecules into smaller, more useful molecules like gasoline.
What is catalytic cracking?
This process involves purging oxygen from a confined space, typically with nitrogen, before entry to reduce hazards.
What is inerting?
Vehicles must yield to these three types of traffic at all times
