When conducting pre-entry and establishing atmospheric monitoring, what three locations should be sampled, and how often?

top, middle, and bottom of the confined space at four-foot intervals.

What is defined as where gasses become layered due to various weights?

Stratified atmospheres

Air monitoring tubing should not be placed where?

Directly into a potentially hazardous material

What are the four types of monitoring?

- General - Perimeter - Confined Space - Personnel

Considering atmospheric monitoring equipment, how many gasses at a time can a Multi-gas monitor system detect?

Up to five gasses: 1. Oxygen 2. LEL 3. Flammable 4. 2-3 Toxic materials

What three tasks are needed to establish a lock-out-tag-out procedure to shut down equipment?

1. Identify the energy 2. Isolate the energy 3. Lock and tag the energy

Considering communications what does the acronym OATH stand for?
