OH Measurement & Sanitation

INSTRUMENT

Light meter- Electronic Illumination Meter (ELM), Lux

Sound Meter- Sound Level Meter, dB(A)

Heat Stress Meter- measure Wet-bulb Globe Temperature Index

[Thermoanometer]- measure Velocity and flow-rate of air

Dust Sampling Trail- Using different Filters

Smoke Tubes- Flow of air. Acid chemical reaction

Detector Tubes- Accurate 25%. Volume each 100cc/compression

Six Stage Viable Particle Sampler- Suction with 6 jet orifices

AIR MEASUREMENT

Qualitative: Ventilator Smoke Tube

Quantitative: Thermoanometer (60-100 linear feet per minutes, lfpm)

DUST SAMPLING TRAIL

Structures- Grit pot -> Air inlet -> Cyclone -> Filter cassette -> Cassette Holder -> Adaptor -> Ruber Tubing -> Tygon Tubing -> Calibrated air sampling pump.

Filter analysed- by Filter Weight Analysis/ Gravimetric

Type of Filter:

• PVC (polyVanyl Chloride)- Total Particulate (TWA-PEL:15mg/m3)

• MCE (Mix Cellulose Ester)- Respirable Particulate (TWA-PEL: 5mg/m3)

Respirable Dust: Aerosol collected by sampler with 4um medical cut point of <1% containing asbestos or quartz
