Section 4 - FIRST AID MEASURES
SWALLOWED
If poisoning occurs, contact a doctor or Poisons Information Centre.
鈥? If swallowed do NOT induce vomiting.
鈥? If vomiting occurs, lean patient forward or place on left side (head-down
position, if possible) to maintain open airway and prevent aspiration.
鈥? Observe the patient carefully.
鈥? Never give liquid to a person showing signs of being sleepy or with reduced
awareness; i.e. becoming unconscious
鈥? Give water to rinse out mouth, then provide liquid slowly and as much as
casualty can comfortably drink.
鈥? Seek medical advice.
EYE
If this product comes in contact with the eyes:
鈥? Wash out immediately with fresh running water.
鈥? Ensure complete irrigation of the eye by keeping eyelids apart and away from
eye and moving the eyelids by occasionally lifting the upper and lower lids.
鈥? If pain persists or recurs seek medical attention.
鈥? Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
SKIN
Brush off dust.
Immediately wash affected areas with water and soap.
If irritation continues, seek medical attention.
INHALED
If skin or hair contact occurs:
鈥? Flush skin and hair with running water (and soap if available).
鈥? Seek medical attention in event of irritation.
NOTES TO PHYSICIAN
Both dermal and oral toxicity of manganese salts is low because of limited
solubility of manganese. No known permanent pulmonary sequelae develop after
acute manganese exposure. Treatment is supportive.
[Ellenhorn and Barceloux: Medical Toxicology]
In clinical trials with miners exposed to manganese-containing dusts, L-dopa
relieved extrapyramidal symptoms of both hypo kinetic and dystonic patients. For
short periods of time symptoms could also be controlled with scopolamine and
amphetamine. BAL and calcium EDTA prove ineffective.

manganous oxide N.E. N.E. 500
Ceiling values were recommended for manganese and compounds in earlier
publications. As manganese is a chronic toxin a TWA is considered more
appropriate. Because workers exposed to fume exhibited manganism at air-borne
concentrations below those that affect workers exposed to dust a lower value has
been proposed to provide an extra margin of safety. This value is still above
that experienced by two workers exposed to manganese fume in the course of one
study.
A number of studies have shown that susceptibility to the effects of manganese
at or about 1 - 5 mg/m鲁 (TWA) can lead to clinical manifestations of manganism
or more commonly to the development of indicators of sub-clinical manganism
(e.g. hand tremor, exaggerated reflexes, short-term memory deficits, poor
psychomotor performance). Controlling long-term exposure to the recommended ES
TWA level or below should provide protection for those individuals susceptible
to neurological effects of prolonged exposure.
PERSONAL PROTECTION
EYE
鈥? Safety glasses with side shields; or as required,
鈥? Chemical goggles.
鈥? 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

ENGINEERING CONTROLS
鈥? Local exhaust ventilation is required where solids are handled as powders or
crystals; even when particulates are relatively large, a certain proportion will
be powdered by mutual friction.
鈥? Exhaust ventilation should be designed to prevent accumulation and
recirculation of particulates in the workplace.
鈥? If in spite of local exhaust an adverse concentration of the substance in air
could occur, respiratory protection should be considered. Such protection might
consist of:
(a): particle dust respirators, if necessary, combined with an absorption
cartridge;
(b): filter respirators with absorption cartridge or canister of the right type;
(c): fresh-air hoods or masks
鈥? Build-up of electrostatic charge on the dust particle, may be prevented by
bonding and grounding.
鈥? Powder handling equipment such as dust collectors, dryers and mills may
require additional protection measures such as explosion venting.
Air contaminants generated in the workplace possess varying "escape" velocities
which, in turn, determine the "capture velocities" of fresh circulating air
required to efficiently remove the contaminant.
Type of Contaminant: Air Speed:
direct "spray " spray painting in 1-2.5 m/s (200-500 f/min.)
shallow "booths " drum "filling "
conveyer "loading " crusher "dusts "
gas discharge (active generation into
zone of rapid air motion)

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
grinding " abrasive "blasting " 2.5-10 m/s (500-2000 f/min.)
"tumbling " high 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 1: Disturbing room air currents
favourable to capture
2: Contaminants of low toxicity or of 2: Contaminants of high toxicity
nuisance value only
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in 4: Small hood-local control only
motion
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 4-10 m/s (800-2000 f/min)
for extraction of crusher dusts generated 2 metres 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.
