Section 4 - FIRST AID MEASURES
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.
SKIN
If skin contact occurs:
路 Immediately remove all contaminated clothing, including footwear.
路 Flush skin and hair with running water (and soap if available).
路 Seek medical attention in event of irritation.
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.
NOTES TO PHYSICIAN
For acute or short-term repeated exposures to formaldehyde:
INGESTION:
路 Patients present early with severe corrosion of the gastro-intestinal tract and
systemic effects.
路 Inflammation and ulceration may progress to strictures.
路 Severe acidosis results from rapid conversion of formaldehyde to formic acid. Coma,
hypotension, renal failure and apnoea complicate ingestion.
路 Decontaminate by dilution with milk or water containing ammonium acetate; vomiting
should be induced. Follow with gastric lavage using a weak ammonia solution (converts
formaldehyde to relatively inert pentamethylenetetramine)
路 Gastric lavage is warranted only in first 15 minutes following ingestion.
SKIN:
路 Formaldehyde can combine with epidermal protein to produce a hapten-protein couple
capable of sensitising T-lymphocytes. Subsequent exposures cause a type IV
hypersensitivity reaction (i.e allergic contact dermatitis). [Ellenhorn & Barceloux:
Medical Toxicology].
Section 5 - FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA
Water spray or fog.
路 Alcohol stable foam.
Dry chemical powder.
FIRE FIGHTING
Alert Fire Brigade and tell them location and nature of hazard.
路 May be violently or explosively reactive.
路 Wear full body protective clothing with breathing apparatus.
路 Prevent, by any means available, spillage from entering drains or water courses.
Use water delivered as a fine spray to control the fire and cool adjacent area.
DO NOT approach containers suspected to be hot.
If safe to do so, remove containers from path of fire.
Equipment should be thoroughly decontaminated after use.

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 133 is taken from the US DOT emergency response guide book.
6 IERG information is derived from CANUTEC - Transport Canada.

INGREDIENT DATA
FORMALDEHYDE:
Odour Threshold Value: 0.98 ppm (recognition)
NOTE: Detector tubes for formaldehyde, measuring in excess of 0.2 ppm are
available commercially.
Formaldehyde vapour exposure:
Primary irritation is dependent on duration of exposure and individual
susceptibility.
The following are typical symptoms encountered at various exposure levels.
0.1 ppm - Lower level of mucous eye, nose and throat irritation
0.8 ppm - Typical threshold of perception
1-2 ppm - Typical threshold of irritation
2-3 ppm - Irritation of eyes, nose and throat
4-5 ppm - Increased irritation, tearing, headache, pungent odour
10-20 ppm - Profuse tearing, severe burning, coughing
50 ppm - Serious bronchial and alveolar damage
100 ppm - Formaldehyde induced chemical pneumonia and death
Despite the intent of the TLV Ceiling recommendation it is believed that
0.3 ppm will not protect that portion of the workforce (up to 20%) reported
to be responsive to low ambient concentrations. Because of the dose-related
carcinogenic activity for rat and mouse inhalation of formaldehyde, the
report of macromolecular adducts in the upper and lower respiratory
tracts of nonhuman primates following inhalation of formaldehyde, the human
case reports of upper respiratory tract malignant melanoma associated with
formaldehyde inhalation and the suggestive epidemiologic data on human
cancer risk, the TLV Committee recommends that workplace formaldehyde air
concentrations be reduced to the lowest possible levels that can be
achieved using engineering controls.

Section 8 - EXPOSURE CONTROLS / 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].
HANDS/FEET

ENGINEERING CONTROLS
Use in a well-ventilated area.
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 Exhaust ventilation should be designed to prevent accumulation and recirculation of
particulates in the workplace.
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
路 Build-up of electrostatic charge on the dust particle, may be prevented by bonding and

grounding.
路 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 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.
In confined spaces where there is inadequate ventilation, wear full-face air supplied
breathing apparatus.

POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
Accidental ingestion of the material may be harmful; animal experiments indicate that
ingestion of less than 150 gram may be fatal or may produce serious damage to the health
of the individual.
Ingestion may result in nausea, abdominal irritation, pain and vomiting.
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
The material may cause severe 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. Repeated exposures may produce severe ulceration.
Regular skin contact may cause brown discolouration with tanning effect, hardening of
skin, with cracking and possible dermatitis following.
Bare unprotected skin should not be exposed to this material.
The material may accentuate any pre-existing dermatitis condition.
INHALED
The material can cause respiratory irritation in some persons. The body's response to
such irritation can cause further lung damage.
CHRONIC HEALTH EFFECTS
Long-term exposure to respiratory irritants may result in disease of the airways
involving difficult breathing and related systemic problems.
Skin contact with the material is more likely to cause a sensitisation reaction in some
persons compared to the general population.
Sensitisation may result in allergic dermatitis responses including rash, itching, hives
or swelling of extremities.
Sensitisation reactions may appear suddenly after repeated
symptom free exposures.

Formaldehyde is ubiquitous in the environment as a contaminant of smoke and as
photochemical smog.
In the atmosphere, formaldehyde both photolyses and reacts with reactive free radicals
(primarily hydroxyl radicals); half-lives in the sunlit tropospheres are 1.25 to 6 hours
for photolysis, and 7.13-71.3 hours for reaction with hydroxyl radicals).
Reaction with nitrate radicals, insignificant during the day, may be an important removal
process at night. Due to its solubility, formaldehyde will efficiently transfer to rain
and surface water; one model predicts dry deposition and wet removal half-lives of 19 and
50 hours, respectively.
In water, formaldehyde will biodegrade to low concentrations within days; adsorption to
sediment and volatilisation are not expected to be significant routes.
In soil, aqueous solutions of formaldehyde leach through the soil; at high concentrations
adsorption to clay minerals may occur. Although biodegradable under both aerobic and
anaerobic conditions the fate of formaldehyde in soil is unclear.
It does not bioconcentrate in the food chain.
