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 145 is taken from the US DOT emergency response guide book.
6 IERG information is derived from CANUTEC - Transport Canada.
EMERGENCY RESPONSE PLANNING GUIDELINES (ERPG)

Section 7 - HANDLING AND STORAGE
(ii) : Cans with friction closures and
(iii) : low pressure tubes and cartridges may be used.
?Where combination packages are used, and the inner packages are of glass, there must be
sufficient inert cushioning material in contact with inner and outer packages
?In addition, where inner packagings are glass and contain liquids of packing group I
there must be sufficient inert absorbent to absorb any spillage, unless the outer
packaging is a close fitting moulded plastic box and the substances are not incompatible
with the plastic.

STORAGE INCOMPATIBILITY
Avoid cross contamination between the two liquid parts of product (kit). If two part
products are mixed or allowed to mix in proportions other than manufacturer's
recommendation, polymerisation with gelation and evolution of heat (exotherm) may occur.
This excess heat may generate toxic vapour.
Avoid any contamination of this material as it is very reactive and any contamination is
potentially hazardous.
?Organic compounds can ignite on contact with concentrated peroxides.
?Strongly reduced material such as sulfides, nitrides, and hydrides may react
explosively with peroxides.
?There are few chemical classes that do not at least produce heat when mixed with
peroxides.
?Many peroxide reactions produce explosions or generate gases (toxic and nontoxic).
STORAGE REQUIREMENTS
Dangerous Goods requirements are that this Organic Peroxide be stored and transported
below its Control Temperature; which is.
?Store in original containers in approved flame-proof area.
?No smoking, naked lights, heat or ignition sources.
?DO NOT store in pits, depressions, basements or areas where vapours may be trapped.
?Keep containers securely sealed.
?Store away from incompatible materials in a cool, dry well ventilated area.

ETHYL ACETATE:
Odour Threshold Value: 6.4-50 ppm (detection), 13.3-75 ppm (recognition)
The TLV-TWA provides a significant margin of safety from the standpoint of
adverse health effects. Unacclimated subjects found the odour
objectionably strong at 200 ppm. Mild nose, eye and throat irritation was
experienced at 400 ppm. Workers exposed regularly at concentrations
ranging from 375 ppm to 1500 ppm for several months showed no unusual
signs or symptoms.
CYCLOHEXANONE PEROXIDE:
No exposure limits set by NOHSC or ACGIH.
DIACETONE ALCOHOL:
Odour Threshold Value: 0.27 ppm (detection), 1.1 ppm (recognition)
The TLV-TWA is thought to be protective against eye, nose and throat
irritation. Eye irritation appeared in the majority of subjects exposed
for 15 minutes to 100 ppm. This concentration also elicited complaints of
nose and throat irritation, objectionable odour and taste.
CYCLOHEXANONE:
Odour Threshold Value: 0.12 ppm (detection and recognition)
Exposure at the TLV-TWA produces minimal irritation and this limit is
significantly lower than the concentration reported to just induce

Exposure at or below the TLV-TWA is thought to minimise irritation and
bleaching of hair.
PERSONAL PROTECTION
EYE
?Chemical goggles.
?Full face shield may be required for supplementary but never for primary protection of
eyes
?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
Suitability and durability of glove type is dependent on usage. Factors such as:
?frequency and duration of contact,
?chemical resistance of glove material,
?glove thickness and
?dexterity,
are important in the selection of gloves.
Wear chemical protective gloves, eg. PVC.
Wear safety footwear or safety gumboots, eg. Rubber.
When handling corrosive liquids, wear trousers or overalls outside of boots, to avoid
spills entering boots.
OTHER
?Overalls.
?PVC Apron.
?PVC protective suit may be required if exposure severe.
?Eyewash unit.
?Ensure there is ready access to a safety shower.
RESPIRATOR
Selection of the Class and Type of respirator will depend upon the level of breathing
zone contaminant and the chemical nature of the contaminant. Protection Factors (defined
as the ratio of contaminant outside and inside the mask) may also be important.

Section 11 - TOXICOLOGICAL INFORMATION
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, pain, vomiting. Vomit entering the lungs by aspiration
may cause potentially lethal chemical pneumonitis.
EYE
The material can produce chemical burns to the eye following direct contact. Vapours or
mists may be extremely irritating.
When applied to the eye(s) of animals, the material produces severe ocular lesions which
are present twenty-four hours or more after instillation.
The liquid produces a high level of eye discomfort and is capable of causing pain and
severe conjunctivitis. Corneal injury may develop, with possible permanent impairment of
vision, if not promptly and adequately treated.
Eye contact with organic peroxides may produce superficial opacity, redness, swelling of
the membranes, and burns on prolonged contact.
SKIN
The material can produce chemical burns following direct contact with the skin.
Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may
produce systemic injury with harmful effects. Examine the skin prior to the use of the
material and ensure that any external damage is suitably protected.
Absorption by skin may readily exceed vapour inhalation exposure. Symptoms for skin
absorption are the same as for inhalation.
Skin contact with the material may be harmful; systemic effects may result following
absorption.
All organic peroxides are irritating to the skin and if allowed to remain on the skin,
may produce inflammation; some are allergenic.
INHALED
Evidence shows, or practical experience predicts, that the material produces irritation
of the respiratory system in a substantial number of individuals following inhalation.
Inhalation hazard is increased at higher temperatures.
If exposure to highly concentrated solvent atmosphere is prolonged this may lead to
narcosis, unconsciousness, even coma and possible death.
Inhalation of vapours may cause drowsiness and dizziness. This may be accompanied by
narcosis, reduced alertness, loss of reflexes, lack of coordination and vertigo.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and by inhalation of
vapours especially at higher temperatures.
Chronic exposure to certain peroxides produces allergic dermatitis (with redness and
scaling of the skin) and asthmatic wheezing.
Chronic solvent inhalation exposures may result in nervous system impairment
and liver and blood changes. [PATTYS].
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.
TOXICITY AND IRRITATION
unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
Asthma-like symptoms may continue for months or even years after exposure to the material
ceases. This may be due to a non-allergenic condition known as reactive airways
dysfunction syndrome (RADS) which can occur following exposure to high levels of highly
irritating compound. Key criteria for the diagnosis of RADS include the absence of
preceding respiratory disease, in a non-atopic individual, with abrupt onset of
persistent asthma-like symptoms within minutes to hours of a documented exposure to the
irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to
severe bronchial hyperreactivity on methacholine challenge testing and the lack of

Section 11 - TOXICOLOGICAL INFORMATION
minimal lymphocytic inflammation, without eosinophilia, have also been included in the
criteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an
infrequent disorder with rates related to the concentration of and duration of exposure
to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that
occurs as result of exposure due to high concentrations of irritating substance (often
particulate in nature) and is completely reversible after exposure ceases. The disorder
is characterised by dyspnea, cough and mucus production.

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 a contact dermatitis (nonallergic). This form of dermatitis is often
characterised by skin redness (erythema) and swelling epidermis. Histologically there may
be intercellular oedema of the spongy layer (spongiosis) and intracellular oedema of the
epidermis.
The substance is classified by IARC as Group 3:
NOT classifiable as to its carcinogenicity to humans.
Evidence of carcinogenicity may be inadequate or limited in animal testing.
