(Not specified))
MATERIAL DATA
These "dusts" have little adverse effect on the lungs and do not produce toxic effects or
organic disease. Although there is no dust which does not evoke some cellular response at
sufficiently high concentrations, the cellular response caused by P.N.O.C.s has the
following characteristics:
路 the architecture of the air spaces remain intact,
路 scar tissue (collagen) is not synthesised to any degree,
路 tissue reaction is potentially reversible.
Extensive concentrations of P.N.O.C.s may:
路 seriously reduce visibility,
路 cause unpleasant deposits in the eyes, ears and nasal passages,
路 contribute to skin or mucous membrane injury by chemical or mechanical action, per se,
or by the rigorous skin cleansing procedures necessary for their removal. [ACGIH]
This limit does not apply:
路 to brief exposures to higher concentrations
路 nor does it apply to those substances that may cause physiological impairment at lower
concentrations but for which a TLV has as yet to be determined.
This exposure standard applies to particles which
路 are insoluble or poorly soluble* in water or, preferably, in aqueous lung fluid (if
data is available) and
路 have a low toxicity (i.e.. are not cytotoxic, genotoxic, or otherwise chemically
reactive with lung tissue, and do not emit ionizing radiation, cause immune sensitization
, or cause toxic effects other than by inflammation or by a mechanism of lung overload).
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields; or as required,
路 Chemical goggles.
路 Contact lenses may pose a special hazard; soft contact lenses may absorb and
concentrate irritants. A written policy document, describing the wearing of lens 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].

ENGINEERING CONTROLS
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 0.25- 0.5 m/s (50- 100 f/min)
from tank (in still air).
aerosols, fumes from pouring operations, 0.5- 1 m/s (100- 200 f/min.)
intermittent container filling, low speed
conveyer transfers, welding, spray drift,
plating acid fumes, pickling (released at low
velocity into zone of active generation)
direct spray, spray painting in shallow booths, 1- 2.5 m/s (200- 500 f/min.)
drum filling, conveyer loading, crusher dusts,
gas discharge (active generation into zone of
rapid air motion)
grinding, abrasive blasting, tumbling, high 2.5- 10 m/s (500- 2000 f/min.)
speed wheel generated dusts (released at high
initial velocity into zone of very high rapid
air motion).
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 1: Disturbing room air currents

2: Contaminants of low toxicity or of nuisance 2: Contaminants of high toxicity

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.

Section 11 - TOXICOLOGICAL INFORMATION
EYE
The material is highly discomforting to the eyes and is capable of causing pain and
severe conjunctivitis. Corneal injury may develop, with possible permanent impairment of
vision, if not promptly and adequately treated.
The material may produce severe irritation to the eye causing pronounced inflammation.
Repeated or prolonged exposure to irritants may produce conjunctivitis.
SKIN
The material is moderately discomforting to the skin.
Prolonged exposure may cause chemical burns.
The material may accentuate any pre-existing skin condition.
The material may cause skin irritation after prolonged or repeated exposure and may
produce on contact skin redness, swelling, the production of vesicles, scaling and
thickening of the skin.
INHALED
The dust may be discomforting to the upper respiratory tract.
Persons with impaired respiratory function, airway diseases and conditions such as
emphysema or chronic bronchitis, may incur further disability if excessive concentrations
of particulate are inhaled.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and inhalation of
generated dusts.
Sensitisation may give severe responses to very low levels of exposure, i.e.
hypersensitivity. Sensitised persons should not be allowed to work in situations where
exposure may occur.
