20
Q

Airflow Volume

A

Specific Quantity of air being pulled into and through the ventilation system

21
Q

Capture Velocity

A

Air Velocity at any point in front of a capture hood opening necessary to overcome opposing air currents and capture contaminated air prior to entering the workers breathing zone

22
Q

Face Velocity

A

Measurement of air at the opening of a local exhaust capture hood

23
Q

Three Components of Airflow

A

Area, Velocity, Airflow Volume

24
Q

Three Types of Pressure Losses

A

Friction Loss, Dynamic Loss, Vena Contracta

25
Q

Friction Loss

A

Due to rubbing of air molecules along the sides of the duct

26
Q

Dynamic Losses

A

Losses due to turbulence

27
Q

Vena Contracta

A

Point where airstream diameter is the smallest

28
Q

Smoke Tubes

A

Determine airflow in or out of a room

29
Q

Magnehelic Gauge

A

Determine what pressure the system is under

30
Q

Balometer

A

Uses hood attachment to funnel airflow and then calculate airflow volume automatically

31
Q

LEV System

A

Designed to capture and remove process emissions prior to their escape into the workplace environment.

32
Q

Manufacturers Guide

A

Should publish the minimum parameters that the ventilation system must meet before the system is deemed operational

33
Q

ACGIH

A

Key parameters that a ventilation system must meet before it is put into place

34
Q

Pre-Survey Form

A

If a ventilation system has already been evaluated, then there is a high probability that a BE technician has already researched the ventilation system key parameters in the IVM or the manufacturer’s literature and annotated those parameters on a pre-survey form.

35
Q

Vapor Calculations

A

Can be an indicator of what might be happening in the environment

36
Q

Air Sampling

A

Provide raw data on how much contaminant is being generated

37
Q

Standards

A

Sometimes specific contaminants can cause more harm to the body in comparison to other chemicals. These chemicals will have special regulations OSHA substance

38
Q

Face Velocity

A

Survey measures the velocity at the face of the hood

39
Q

Termoanemometer

A

This type of instrument employs the principle that the amount of heat removed by an airstream passing a heated object is related to the velocity of the airstream

40
Q

Inclined Manometer

A

Uses a Pitot tube allowing the user to record pressure inside the duct of the ventilation system; filled with red gauge oil, with a specific gravity of 0.826

41
Q

Pitot Traverse

A

Used to perform duct velocity or transport velocity surveys as well as static pressure checks.

42
Q

Operations and Maintenance Procedures for Ventilation Systems

A

Well-Maintained Filter System, Regular Maintenance, Good Housekeeping, Air Intakes in non-contaminated locations, Components dry

43
Q

Cleaning/Sanitizing Respirators

A

respirators must be Cleaned and disinfected IAW 29 CFR 1910.134 App. B-2 and AFI 48-137 regularly.

44
Q

Facepiece

A

> Rips, tears, cracks, and/or holes
Deformation of the natural shape
Cracked, scratched, or loose-fitting lenses
Broken or missing mounting clips

45
Q

Head Straps/Harness

A

> Loss of elasticity
Broken buckles or attachments
Breaks or tears

46
Q

Exhalation/Inhalation Valves

A 
> Detergent residue or dust on valve seal
> Proper installation
> Rips, tears, cracks, and/or holes
> Missing/defective valve cover
> Pliability
47
Q

Air-purifying Element

A

> Proper type of filter for the contaminant(s)
Missing or worn gaskets
Worn threads
Cracks or dents in the housing

48
Q

Workplace Specific Operating Instructions

A

Supervisors of workplaces in which respiratory protection is used must develop a written plan as required by 29 CFR 1910.134
