Section 6 - ACCIDENTAL RELEASE MEASURES
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 129 is taken from the US DOT emergency response guide book.
6 IERG information is derived from CANUTEC - Transport Canada.

protective action is:

ODOUR SAFETY FACTOR (OSF)
OSF=38 (ACETONE)
Exposed individuals are reasonably expected to be warned, by smell, that the Exposure
Standard is being exceeded.
Odour Safety Factor (OSF) is determined to fall into either Class A or B.
The Odour Safety Factor (OSF) is defined as:
OSF= Exposure Standard (TWA) ppm/ Odour Threshold Value (OTV) ppm
Classification into classes follows:
Class OSF Description
A 550 Over 90% of exposed individuals
are aware by smell that the
Exposure Standard (TLV- TWA for
example) is being reached, even
when distracted by working
activities
B 26- 550 As " A" for 50- 90% of persons
being distracted
C 1- 26 As " A" for less than 50% of
persons being distracted
D 0.18- 1 10- 50% of persons aware of
being tested perceive by smell
that the Exposure Standard is
being reached
E <0.18 As " D" for less than 10% of
persons aware of being tested
.
MATERIAL DATA
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.
INGREDIENT DATA
WATER:
No exposure limits set by NOHSC or ACGIH.

.
Odour Threshold Value: 3.6 ppm (detection), 699 ppm (recognition)
Saturation vapour concentration: 237000 ppm @ 20 C
NOTE: Detector tubes measuring in excess of 40 ppm, are available.
Exposure at or below the recommended TLV-TWA is thought to protect the
worker against mild irritation associated with brief exposures and the
bioaccumulation, chronic irritation of the respiratory tract and headaches
associated with long-term acetone exposures. The NIOSH REL-TWA is
substantially lower and has taken into account slight irritation
experienced by volunteer subjects at 300 ppm. Mild irritation to
acclimatised workers begins at about 750 ppm - unacclimatised subjects
will experience irritation at about 350-500 ppm but acclimatisation can
occur rapidly. Disagreement between the peak bodies is based largely on
the view by ACGIH that widespread use of acetone, without evidence of
significant adverse health effects at higher concentrations, allows
acceptance of a higher limit.
Half-life of acetone in blood is 3 hours which means that no adjustment
for shift-length has to be made with reference to the standard 8 hour/day,
40 hours per week because body clearance occurs within any shift with low
potential for accumulation.
A STEL has been established to prevent excursions of acetone vapours that
could cause depression of the central nervous system.

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

Use in a well-ventilated area. or Local exhaust ventilation may be required for safe
working, i.e. to keep exposures below required standards, otherwise PPE is required.
General exhaust is adequate under normal operating conditions. Local exhaust ventilation
may be required in special circumstances. If risk of overexposure exists, wear approved
respirator. Supplied-air type respirator may be required in special circumstances.
Correct fit is essential to ensure adequate protection. Provide adequate ventilation in
warehouses and enclosed 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., evaporating 0.25- 0.5 m/s (50- 100 f/min)
from tank (in still air).
aerosols, fumes from pouring operations, 0.5- 1 m/s (100- 200 f/min.)
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 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 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.

and it is slowly absorbed.
Toxic effects may result from skin absorption.
Absorption by skin may readily exceed vapour inhalation exposure. Symptoms for skin
absorption are the same as for inhalation.
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.
INHALED
The vapour is discomforting to the upper respiratory tract.
Inhalation hazard is increased at higher temperatures.
Inhalation of high concentrations of gas/vapour causes lung irritation with coughing and
nausea, central nervous depression with headache and dizziness, slowing of reflexes,
fatigue and inco-ordination.
If exposure to highly concentrated solvent atmosphere is prolonged this may lead to
narcosis, unconsciousness, even coma and possible death.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are usually by skin contact.

In air, acetone is lost by photolysis and reaction with photochemically
produced hydroxyl radicals; the estimated half-life of these combined
processes is about 22 days. The relatively long half-life allows acetone
to be transported long distances from its emission source.
Acetone is highly soluble and slightly persistent in water, with a
half-life of about 20 hours; it is minimally toxic to aquatic life.
Acetone released to soil volatilises although some may leach into the
ground where it rapidly biodegrades.
Acetone does not concentrate in the food chain.
