Section 7 - HANDLING AND STORAGE
路 Use good occupational work practice.
路 Observe manufacturer's storing and handling recommendations.
路 Atmosphere should be regularly checked against established exposure standards to ensure
safe working conditions are maintained.
SUITABLE CONTAINER
路 Lined metal can, lined metal pail/ can.
路 Plastic pail.
路 Polyliner drum.
路 Packing as recommended by manufacturer.
路 Check all containers are clearly labelled and free from leaks.
STORAGE INCOMPATIBILITY
Metals and their oxides or salts may react violently with chlorine trifluoride. Chlorine
trifluoride is a hypergolic oxidiser. It ignites on contact (without external source of
heat or ignition) with recognised fuels - contact with these materials, following an
ambient or slightly elevated temperature, is often violent and may produce ignition. The
state of subdivision may affect the results.
Contact with acid generates carbon dioxide gas, which may pressurise and
then rupture closed containers
STORAGE REQUIREMENTS
路 Store in original containers.
路 Keep containers securely sealed.
路 Store in a cool, dry, well-ventilated area.
路 Store away from incompatible materials and foodstuff containers.
路 Protect containers against physical damage and check regularly for leaks.
路 Observe manufacturer's storing and handling recommendations.

MATERIAL DATA
Sensory irritants are chemicals that produce temporary and undesirable side-effects on
the eyes, nose or throat. Historically occupational exposure standards for these
irritants have been based on observation of workers' responses to various airborne
concentrations. Present day expectations require that nearly every individual should be
protected against even minor sensory irritation and exposure standards are established
using uncertainty factors or safety factors of 5 to 10 or more. On occasion animal no
-observable-effect-levels (NOEL) are used to determine these limits where human results
are unavailable. An additional approach, typically used by the TLV committee (USA) in

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
determining respiratory standards for this group of chemicals, has been to assign ceiling
values (TLV C) to rapidly acting irritants and to assign short-term exposure limits (TLV
STELs) when the weight of evidence from irritation, bioaccumulation and other endpoints
combine to warrant such a limit. In contrast the MAK Commission (Germany) uses a five
-category system based on intensive odour, local irritation, and elimination half-life.
However this system is being replaced to be consistent with the European Union (EU)
Scientific Committee for Occupational Exposure Limits (SCOEL); this is more closely
allied to that of the USA.
OSHA (USA) concluded that exposure to sensory irritants can:
路 cause inflammation
路 cause increased susceptibility to other irritants and infectious agents
路 lead to permanent injury or dysfunction
路 permit greater absorption of hazardous substances and
路 acclimate the worker to the irritant warning properties of these substances thus
increasing the risk of overexposure.
The TLV-TWA is thought to be protective against the significant risk of
physical irritation associated with exposure.
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields.
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].
HANDS/FEET
Experience indicates that the following polymers are suitable as glove materials for
protection against undissolved, dry solids.
路 polychloroprene
路 nitrile rubber
路 butyl rubber
路 fluorocaoutchouc
路 polyvinyl chloride
Gloves should be examined for wear and/ or degradation constantly.
Suitability and durability of glove type is dependent on usage. Factors such as:
路 frequency and duration of contact,
路 chemical resistance of glove material,
路 glove thickness and
路 dexterity,
are important in the selection of gloves.

ENGINEERING CONTROLS
路 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.
路 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.
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:
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
capture
2: Contaminants of low toxicity or of nuisance 2: Contaminants of high toxicity
value only.
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 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.

Section 11 - TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
The material has NOT been classified by EC Directives or other classification systems as
"harmful by ingestion". This is because of the lack of corroborating animal or human
evidence. The material may still be damaging to the health of the individual, following
ingestion, especially where pre-existing organ (eg. liver, kidney) damage is evident.
Present definitions of harmful or toxic substances are generally based on doses producing
mortality rather than those producing morbidity (disease, ill-health). Gastrointestinal
tract discomfort may produce nausea and vomiting. In an occupational setting however,
ingestion of insignificant quantities is not thought to be cause for concern.
EYE
There is evidence that material may produce eye irritation in some persons and produce
eye damage 24 hours or more after instillation. Severe inflammation may be expected with

pain. There may be damage to the cornea. Unless treatment is prompt and adequate there
may be permanent loss of vision. Conjunctivitis can occur following repeated exposure.
SKIN
Skin contact is not thought to have harmful health effects (as classified under EC
Directives); the material may still produce health damage following entry through wounds,
lesions or abrasions.
There is some evidence to suggest that the material may cause moderate inflammation of
the skin either following direct contact or after a delay of some time. Repeated exposure
can cause contact dermatitis which is characterised by redness, swelling and blistering.
INHALED
The material is not thought to produce adverse health effects or irritation of the
respiratory tract (as classified by EC Directives using animal models). Nevertheless,
good hygiene practice requires that exposure be kept to a minimum and that suitable
control measures be used in an occupational setting.
Not normally a hazard due to non-volatile nature of product.
CHRONIC HEALTH EFFECTS
Long-term exposure to the product is not thought to produce chronic effects adverse to
the health (as classified by EC Directives using animal models); nevertheless exposure by
all routes should be minimised as a matter of course.
Long term exposure to high dust concentrations may cause changes in lung function i.e.
pneumoconiosis; caused by particles less than 0.5 micron penetrating and remaining in the
lung. Prime symptom is breathlessness; lung shadows show on X-ray.
TOXICITY AND IRRITATION
unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
TOXICITY IRRITATION
Oral (Rat) LD50: 6450 mg/kg Skin (rabbit): 500 mg/24h- Moderate
Eye (rabbit): 0.75 mg/24h - SEVERE
The material may produce severe irritation to the eye causing pronounced inflammation.
Repeated or prolonged exposure to irritants may produce conjunctivitis.
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.
No evidence of carcinogenic properties. No evidence of mutagenic or
teratogenic effects.
