HEALTH HAZARD
ACUTE HEALTH EFFECTS
SWALLOWED
Considered an unlikely route of entry in commercial/industrial environments
Overexposure is unlikely in this form.
The liquid is harmful if swallowed and is capable of causing severe cold burns
EYE
The vapour is non-irritating to the eyes
The liquid is capable of causing severe cold burns
SKIN
Vapourising liquid causes rapid cooling and contact may cause cold burns,
frostbite.
INHALED
Material is highly volatile and may quickly form a concentrated atmosphere in
confined or unventilated areas. Vapour is heavier than air and may displace and
replace air in breathing zone, acting as a simple asphyxiant. This may happen
with little warning of overexposure.
Symptoms of asphyxia (suffocation) may include headache, dizziness, shortness
of breath, muscular weakness, drowsiness and ringing in the ears. If the
asphyxia is allowed to progress, there may be nausea and vomiting, further
physical weakness and unconsciousness and, finally, convulsions, coma and
death. Significant concentrations of the non-toxic gas reduce the oxygen level
in the air. As the amount of oxygen is reduced from 21 to 14 volume %, the
pulse rate accelerates and the rate and volume of breathing increase. The
ability to maintain attention and think clearly is diminished and muscular
coordination is somewhat disturbed. As oxygen decreases from 14-10% judgement
becomes faulty; severe injuries may cause no pain. Muscular exertion leads to
rapid fatigue. Further reduction to 6% may produce nausea and vomiting and the
ability to move may be lost. Permanent brain damage may result even after
resuscitation at exposures to this lower oxygen level. Below 6% breathing is in
gasps and convulsions may occur. Inhalation of a mixture containing no oxygen
may result in unconsciousness from the first breath and death will follow in a
few minutes.
WARNING:Intentional misuse by concentrating/inhaling contents may be lethal.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are usually by inhalation of vapour/spray mist and
skin contact / eye contact
As with any chemical product, contact with unprotected bare skin; inhalation of
vapour, mist or dust in work place atmosphere; or ingestion in any form, should
be avoided by observing good occupational work practice.
FIRST AID
SWALLOWED
If swallowed do NOT induce vomiting.
If vomiting occurs, lean patient forward or place on left side (head-down
position, if possible) to maintain open airway and prevent aspiration.
Observe the patient carefully.
Never give liquid to a person showing signs of being sleepy or with reduced
awareness; i.e. becoming unconscious.
Give water to rinse out mouth, then provide liquid slowly and as much as
casualty can comfortably drink.
Seek medical advice.
EYE
If this product comes in contact with the eyes:
Immediately hold eyelids apart and flush the eye continuously with running
water.
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.
Continue flushing until advised to stop by the Poisons Information Centre or a
doctor, or for at least 15 minutes.
Transport to hospital or doctor without delay.
Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
SKIN
If skin or hair contact occurs:
Flush skin and hair with running water (and soap if available).
Seek medical attention in event of irritation.
In case of cold burns (frost-bite):
Bathe the affected area immediately in cold water for 10 to 15 minutes,
immersing if possible and without rubbing.
DO NOT apply hot water or radiant heat.
Apply a clean, dry dressing.
Transport to hospital, or doctor.
INHALED
If fumes or combustion products are inhaled remove from contaminated area.
Lay patient down. Keep warm and rested.
Prostheses such as false teeth, which may block airway, should be removed,
where possible, prior to initiating first aid procedures.
Apply artificial respiration if not breathing, preferably with a demand valve
resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if
necessary.
Transport to hospital, or doctor, without delay.
ADVICE TO DOCTOR
Treat symptomatically.
TOXICITY AND IRRITATION
No data for Zeus Dust Away.
TETRAFLUOROETHANE:
No significant acute toxicological data identified in literature search.
PRECAUTIONS FOR USE
EXPOSURE STANDARDS
No data for Zeus Dust Away.
EXPOSURE STANDARDS FOR MIXTURE
"Worst Case" computer-aided prediction of vapour components/concentrations:
Composite Exposure Standard for Mixture (TWA) (mg/m鲁): 4240 mg/m鲁
If the breathing zone concentration of ANY of the components listed below is
exceeded, "Worst Case" considerations deem the individual to be over
overexposed.
Component Breathing Zone ppm Breathing Zone mg/m鲁 Mixture Conc: (%)
tetrafluoroethane 1000 4240 100
INGREDIENT DATA
TETRAFLUOROETHANE:
ES TWA: 1000 ppm, 4240 mg/m鲁
OES TWA: 1000 ppm, 4240 mg/m鲁
Studies show that HFC 134a is practically nontoxic by inhalation. The
acute lethal effects occur at levels exceeding 500000 ppm whilst the
threshold for cardiac sensitisation occurs at about 75000 ppm. Repeated
exposures at 50000 ppm for 13 weeks did not produce significant toxicity
in animals. Limited studies have shown the substance not to be a
carcinogen, or to exhibit mutagenic effects. Exposures up to 300000 ppm
and 40000 ppm did not produce teratogenic effects in rats and rabbits
respectively. The workplace environmental exposure level (WEEL),
recommended by the AIHA, is thought to be protective against cardiac
sensitisation and systemic injury.
ENGINEERING CONTROLS
Use in a well-ventilated area
General exhaust is adequate under normal operating conditions. If risk of
overexposure exists, wear SAA 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., 0.25-0.5 m/s (50-100 f/min)
evaporating from tank (in still air)
aerosols, fumes from pouring 0.5-1 m/s (100-200 f/min.)
operations, 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 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)
grinding, abrasive blasting, tumbling, 2.5-10 m/s (500-2000 f/min.)
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 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.

PROTECTIVE ACTIONS FOR SPILL
>From IERG (Canada/Australia)
Isolation Distance -
Downwind Protection Distance 8 metres
FOOTNOTES
1 PROTECTIVE ACTION ZONE is defined as the area in which people are at risk
of harmful exposure. This zone assumes that random changes in wind direction
confines the vapour plume to an area within 30 degrees on either side of the
predominant wind direction, resulting in a crosswind protective action distance
equal to the downwind protective action distance.
2 PROTECTIVE ACTIONS should be initiated to the extent possible, beginning with
those closest to the spill and working away from the site in the downwind
direction. Within the protective action zone a level of vapour concentration
may exist resulting in nearly all unprotected persons becoming incapacitated
and unable to take protective action and/or incurring serious or irreversible
health effects.
3 INITIAL ISOLATION ZONE is determined as an area, including upwind of the
incident, within which a high probability of localised wind reversal may
expose nearly all persons without appropriate protection to life-threatening
concentrations of the material.
4 SMALL SPILLS involve a leaking package of 200 litres (55 US gallons) or less,
such as a drum (jerrican or box with inner containers). Larger packages leaking
less than 200 litres and compressed gas leaking from a small cylinder are also
considered "small spills".
LARGE SPILLS involve many small leaking packages or a leaking package of
greater than 200 litres, such as a cargo tank, portable tank or a "one-tonne"
compressed gas cylinder.
5 Guide 126 is taken from the US DOT emergency response guide book.
6 IERG information is derived from CANUTEC - Transport Canada.
