Use and Care Manual

General exhaust is adequate under normal operating conditions. Local exhaust ventilation may be required in specific
circumstances. If risk of overexposure exists, wear approved respirator. Correct fit is essential to obtain adequate protection.
Provide adequate ventilation in warehouse or closed storage areas. Air contaminants generated in the workplace possess
varying 'escape' velocities which, in turn, determine the 'capture velocities' of fresh circulating air required to effectively remove
the contaminant.
Type of Contaminant:
Air Speed:
solvent, vapours, degreasing etc., evaporating from tank (in still air).
0.25-0.5 m/s
(50-100 f/min)
aerosols, fumes from pouring operations, intermittent container filling, low speed conveyer transfers,
welding, spray drift, plating acid fumes, pickling (released at low velocity into zone of active generation)
0.5-1 m/s (100-200
f/min.)
direct spray, spray painting in shallow booths, drum filling, conveyer loading, crusher dusts, gas discharge
(active generation into zone of rapid air motion)
1-2.5 m/s (200-500
f/min.)
grinding, abrasive blasting, tumbling, high speed wheel generated dusts (released at high initial velocity
into zone of very high rapid air motion).
2.5-10 m/s
(500-2000 f/min.)
Within each range the appropriate value depends on:
Lower end of the range
Upper end of the range
1: Room air currents minimal or favourable to capture
1: Disturbing room air currents
2: Contaminants of low toxicity or of nuisance value only.
2: Contaminants of high toxicity
3: Intermittent, low production.
3: High production, heavy use
4: Large hood or large air mass in motion
4: Small hood-local control only
Simple theory shows that air velocity falls rapidly with distance away from the opening of a simple extraction pipe. Velocity
generally decreases with the square of distance from the extraction point (in simple cases). Therefore the air speed at the
extraction point should be adjusted, accordingly, after reference to distance from the contaminating source. The air velocity at the
extraction fan, for example, should be a minimum of 1-2 m/s (200-400 f/min) for extraction of solvents generated in a tank 2
meters distant from the extraction point. Other mechanical considerations, producing performance deficits within the extraction
apparatus, make it essential that theoretical air velocities are multiplied by factors of 10 or more when extraction systems are
installed or used.
Personal protection
Eye and face protection
Safety glasses with side shields.
Chemical goggles.
Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy
document, describing the wearing of lenses or restrictions on use, should be created for each workplace or task. This should
include a review of lens absorption and adsorption for the class of chemicals in use and an account of injury experience.
Medical and first-aid personnel should be trained in their removal and suitable equipment should be readily available. In the
event of chemical exposure, begin eye irrigation immediately and remove contact lens as soon as practicable. Lens should
be removed at the first signs of eye redness or irritation - lens should be removed in a clean environment only after workers
have washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59], [AS/NZS 1336 or national equivalent]
