ANNEXURE I<br />
LIST OF BASIC EQUIPMENT<br />
1. Airborne contamin<strong>an</strong>ts (hazardous chemicals, lead <strong>an</strong>d <strong>as</strong>bestos)<br />
• Personal Sampling Pump/s (PSP) with a const<strong>an</strong>t airflow system. Pump must have variable flow<br />
settings to accommodate low flow rates <strong>as</strong> well<br />
• Primary calibration st<strong>an</strong>dard i.e. electronic calibration instrument or <strong>an</strong> inverted burette able to<br />
calibrate PSP to a known flow rate<br />
• Detector tubes <strong>for</strong> me<strong>as</strong>uring g<strong>as</strong> or vapour (including detector tube pump i.e. bellow pump)<br />
• Will be <strong>an</strong> adv<strong>an</strong>tage if available: direct reading instruments <strong>for</strong> airborne g<strong>as</strong>es <strong>an</strong>d vapours (real<br />
time qu<strong>an</strong>tification) or direct reading diffusion tubes/badges<br />
• Ph<strong>as</strong>e contr<strong>as</strong>t microscope fitted with a Walter-Beckett graticule <strong>for</strong> <strong>as</strong>bestos counting will be <strong>an</strong><br />
adv<strong>an</strong>tage<br />
• Correct sample media (filters <strong>an</strong>d sorbent tubes), sample heads (i.e. open face, <strong>an</strong>tistatic cowl),<br />
cyclones <strong>an</strong>d other consumables are import<strong>an</strong>t.<br />
2. Noise<br />
• Integrating sound level meter that complies at le<strong>as</strong>t with the accuracy requirements specified <strong>for</strong> a<br />
type 2 instrument in SANS 61672-1 <strong>an</strong>d SANS 61672-2<br />
• Sound calibrator that complies with the requirements prescribed <strong>for</strong> a type 2 calibrator in SANS<br />
60942<br />
• Personal sound exposure meter (noise dose meter) that comply with the relev<strong>an</strong>t accuracy<br />
requirements of IEC 61252 (<strong>an</strong>d its calibrator) <strong>for</strong> personal exposure me<strong>as</strong>urements will also be <strong>an</strong><br />
adv<strong>an</strong>tage<br />
• A type 1 SLM with frequency <strong>an</strong>alyser (<strong>an</strong>d its calibrator) will again be <strong>an</strong> adv<strong>an</strong>tage, especially due<br />
to accuracy, sound integrating properties <strong>an</strong>d <strong>for</strong> noise control purposes.<br />
3. Illumination<br />
• Photometer (cosine calibrated <strong>an</strong>d colour corrected), e.g. Lux meter.<br />
4. Heat Stress<br />
• Instrument/s able to me<strong>as</strong>ure the following environmental parameters:<br />
- Air temperature or dry bulb<br />
- Humidity or wet bulb<br />
- Radi<strong>an</strong>t temperature or globe bulb<br />
- Air velocity<br />
• I.e. whirling hygrometer, globe thermometer, kata thermometer or <strong>an</strong>emometer (hotwire or v<strong>an</strong>e) or<br />
• Integrated electronic instrumentation i.e. WBGT thermal environmental meter.<br />
5. Cold Stress<br />
• Dry bulb thermometer <strong>an</strong>d <strong>an</strong>emometer (hotwire).<br />
6. Ventilation<br />
• Hot wire <strong>an</strong>emometer<br />
• Pitot static tube<br />
• M<strong>an</strong>ometer.<br />
