Section 4 - FIRST AID MEASURES
路 Seek medical advice.
Immediately transport to hospital or doctor.
DO NOT delay.
EYE
If this product comes in contact with the eyes:
路 Immediately hold eyelids apart and flush the eye continuously with running water.
路 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.
路 Continue flushing until advised to stop by the Poisons Information Centre or a doctor,
or for at least 15 minutes.
路 Transport to hospital or doctor without delay.
路 Removal of contact lenses after an eye injury should only be undertaken by skilled
personnel.
Immediately transport to hospital or doctor.
DO NOT delay.
SKIN
If skin or hair contact occurs:
路 Immediately flush body and clothes with large amounts of water, using safety shower if
available.
路 Quickly remove all contaminated clothing, including footwear.
路 Wash skin and hair with running water. Continue flushing with water until advised to
stop by the Poisons Information Centre.
路 Transport to hospital, or doctor.
DO NOT delay.
INHALED
路 If fumes or combustion products are inhaled remove from contaminated area.
路 Lay patient down. Keep warm and rested.
路 Prostheses such as false teeth, which may block airway, should be removed, where
possible, prior to initiating first aid procedures.
路 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.
路 Transport to hospital, or doctor, without delay.
NOTES TO PHYSICIAN
For acute or short term repeated exposures to strong acids:
路 Airway problems may arise from laryngeal edema and inhalation exposure. Treat with 100%
oxygen initially.
路 Respiratory distress may require cricothyroidotomy if endotracheal intubation is
contraindicated by excessive swelling
路 Intravenous lines should be established immediately in all cases where there is
evidence of circulatory compromise.
路 Strong acids produce a coagulation necrosis characterised by formation of a coagulum
(eschar) as a result of the dessicating action of the acid on proteins in specific
tissues.
INGESTION:
路 Immediate dilution (milk or water) within 30 minutes post ingestion is recommended.
路 DO NOT attempt to neutralise the acid since exothermic reaction may extend the
corrosive injury.
路 Be careful to avoid further vomit since re-exposure of the mucosa to the acid is
harmful. Limit fluids to one or two glasses in an adult.
路 Charcoal has no place in acid management.
路 Some authors suggest the use of lavage within 1 hour of ingestion.
SKIN:
路 Skin lesions require copious saline irrigation. Treat chemical burns as thermal burns
with non-adherent gauze and wrapping.
路 Deep second-degree burns may benefit from topical silver sulfadiazine.

Section 4 - FIRST AID MEASURES
路 Eye injuries require retraction of the eyelids to ensure thorough irrigation of the
conjuctival cul-de-sacs. Irrigation should last at least 20-30 minutes. DO NOT use
neutralising agents or any other additives. Several litres of saline are required.
路 Cycloplegic drops, (1% cyclopentolate for short-term use or 5% homatropine for longer
term use) antibiotic drops, vasoconstrictive agents or artificial tears may be indicated
dependent on the severity of the injury.
路 Steroid eye drops should only be administered with the approval of a consulting
ophthalmologist).

Section 6 - ACCIDENTAL RELEASE MEASURES
Downwind Protection Distance 250 metres
IERG Number 40
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 157 is taken from the US DOT emergency response guide book.
6 IERG information is derived from CANUTEC - Transport Canada.
EMERGENCY RESPONSE PLANNING GUIDELINES (ERPG)
The maximum airborne concentration below which it is believed that nearly all individuals could be exposed
for up to one hour WITHOUT experiencing or developing
life-threatening health effects is:
nitric acid 78 ppm
irreversible or other serious effects or symptoms which could impair an individual's ability to take
protective action is:
nitric acid 6 ppm
other than mild, transient adverse effects without perceiving a clearly defined odour is:

PERSONAL PROTECTION
EYE
路 Chemical goggles.
路 Full face shield may be required for supplementary but never for primary protection of
eyes
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
Bare unprotected skin should not be exposed to this material.
Impervious, gauntlet length gloves. i.e Butyl rubber gloves or Neoprene rubber gloves or
