POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
The material has NOT been classified as "harmful by ingestion". This is because
of the lack of corroborating animal or human evidence. The material may still be
damaging to the health of the individual, following ingestion, especially where
pre-existing organ (e.g. liver, kidney) damage is evident. Present definitions
of harmful or toxic substances are generally based on doses producing mortality
(death) rather than those producing morbidity (disease, ill-health).
Gastrointestinal tract discomfort may produce nausea and vomiting. In an
occupational setting however, unintentional ingestion is not thought to be cause
for concern.
EYE
There is some evidence to suggest that this material can cause
eye irritation and damage in some persons.
SKIN
The material is not thought to produce adverse health effects or skin irritation
following contact (as classified using animal models). Nevertheless, good
hygiene practice requires that exposure be kept to a minimum and that suitable
gloves be used in an occupational setting.
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.
INHALED
There is some evidence to suggest that this material, if inhaled, can irritate
the throat and lungs of some persons.
Inhalation of dusts, generated by the material during the course of normal
handling, may be damaging to the health of the individual.
Effects on lungs are significantly enhanced in the presence of respirable
particles.
CHRONIC HEALTH EFFECTS
Repeated exposures, in an occupational setting, to high levels of fine- divided
dusts may produce a condition known as pneumoconiosis which is the lodgement of
any inhaled dusts in the lung irrespective of the effect. This is particularly
true when a significant number of particles less than 0.5 microns (1/50,000
inch), are present. Lung shadows are seen in the X-ray. Symptoms of
pneumoconiosis may include a progressive dry cough, shortness of breath on
exertion, increased chest expansion, weakness and weight loss. As the disease
progresses the cough produces a stringy mucous, vital capacity decreases further
and shortness of breath becomes more severe. Pneumoconiosis is the accumulation
of dusts in the lungs and the tissue reaction in its presence. It is further
classified as being of noncollagenous or collagenous types. Noncollagenous
pneumoconiosis, the benign form, is identified by minimal stromal reaction,
consists mainly of reticulin fibres, an intact alveolar architecture and is
potentially reversible. Substance accumulation, in the human body, may occur and
may cause some concern following repeated or long-term occupational exposure.

Section 3 - HAZARDS IDENTIFICATION
There has been some concern that this material can cause cancer or mutations but
there is not enough data to make an assessment. There is insufficient evidence
to suggest that exposure to carbon black causes increased susceptibility to
cancer or other ill effects. Some lung changes can occur after a prolonged
period of exposure as well as increased strain on the right side of the heart.
Section 4 - FIRST AID MEASURES
SWALLOWED
- Immediately give a glass of water.
- First aid is not generally required. If in doubt, contact a Poisons
Information Center or a doctor.
EYE
If this product comes in contact with the eyes:
- Wash out immediately with fresh 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.
- If pain persists or recurs seek medical attention.
- 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.
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.

Section 5 - FIRE FIGHTING MEASURES
- Water spray or fog - Large fires only.
FIRE FIGHTING
- Alert Emergency Responders and tell them location and nature of hazard.
- Wear breathing apparatus plus protective gloves.
- Prevent, by any means available, spillage from entering drains or water
course.
- Use water delivered as a fine spray to control fire and cool adjacent area.
- DO NOT approach containers suspected to be hot.
- Cool fire exposed containers with water spray from a protected location.
- If safe to do so, remove containers from path of fire.
- Equipment should be thoroughly decontaminated after use.
GENERAL FIRE HAZARDS/HAZARDOUS COMBUSTIBLE PRODUCTS
- Solid which exhibits difficult combustion or is difficult to ignite.
- Avoid generating dust, particularly clouds of dust in a confined or
unventilated space as dusts may form an explosive mixture with air, and any
source of ignition, i.e. flame or spark, will cause fire or explosion. Dust
clouds generated by the fine grinding of the solid are a particular hazard;
accumulations of fine dust may burn rapidly and fiercely if ignited.
- Dry dust can be charged electrostatically by turbulence, pneumatic transport,
pouring, in exhaust ducts and during transport.
- Build-up of electrostatic charge may be prevented by bonding and grounding.
- Powder handling equipment such as dust collectors, dryers and mills may
require additional protection measures such as explosion venting.
Combustion products include, carbon dioxide (CO2), other pyrolysis products
typical of burning organic material.
May emit poisonous fumes.
May emit corrosive fumes.
FIRE INCOMPATIBILITY
Avoid contamination with oxidizing agents i.e. nitrates, oxidizing acids,
chlorine bleaches, pool chlorine etc. as ignition may result.
PERSONAL PROTECTION

Section 7 - HANDLING AND STORAGE
PROCEDURE FOR HANDLING
NOTE: Wet, activated carbon removes oxygen from the air thus producing a severe
hazard to workers inside carbon vessels and in enclosed or confined spaces where
activated carbons might accumulate. Before entry to such areas, sampling and
test procedures for low oxygen levels should be undertaken; control conditions
should be established to ensure the availability of adequate oxygen supply.
- Avoid all personal contact, including inhalation.
- Wear protective clothing when risk of exposure occurs.
- Use in a well-ventilated area.
- Prevent concentration in hollows and sumps.
- DO NOT enter confined spaces until atmosphere has been checked.
- DO NOT allow material to contact humans, exposed food or food utensils.
- Avoid contact with incompatible materials.
- When handling, DO NOT eat, drink or smoke.
- Keep containers securely sealed when not in use.
- Avoid physical damage to containers.
- Always wash hands with soap and water after handling.
- Work clothes should be laundered separately.
- Launder contaminated clothing before re-use.
- Use good occupational work practice.
- Observe manufacturer's storing and handling recommendations.
- Atmosphere should be regularly checked against established exposure standards
to ensure safe working conditions are maintained.
RECOMMENDED STORAGE METHODS

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
The local concentration of material, quantity and
conditions of use determine the type of personal
protective equipment required.
Use appropriate NIOSH-certified respirator based on informed professional
judgement. In conditions where no reasonable estimate of exposure can be
made, assume the exposure is in a concentration IDLH and use NIOSH-certified
full face pressure demand SCBA with a minimum service life of 30 minutes, or
a combination full facepiece pressure demand SAR with auxiliary self-contained
air supply. Respirators provided only for escape from IDLH atmospheres shall be
NIOSH-certified for escape from the atmosphere in which they will be used.
ENGINEERING CONTROLS
- 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.
- Exhaust ventilation should be designed to prevent accumulation and
recirculation of particulates in the workplace.
- 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
- Build-up of electrostatic charge on the dust particle, may be prevented by
bonding and grounding.
- Powder handling equipment such as dust collectors, dryers and mills may
require additional protection measures such as explosion venting.

CONDITIONS CONTRIBUTING TO INSTABILITY
- Presence of incompatible materials.
- Product is considered stable.
- Hazardous polymerization will not occur.
STORAGE INCOMPATIBILITY
Activated carbon, when exposed to air, represents a potential fire hazard due to
a high surface area and adsorptive capacity. Freshly prepared material may
ignite spontaneously in the presence of air especially at high humidity.
Spontaneous combustion in air may occur at 90-100 deg. C. The presence of
moisture in air facilitates the ignition. Drying oils and oxidising oils promote
spontaneous heating and ignition; contamination with these must be avoided.
Unsaturated drying oils (linseed oil etc.) may ignite following adsorption owing
to an enormous increase in the surface area of oil exposed to air; the rate of
oxidation may also be catalysed by metallic impurities in the carbon. A similar,
but slower effect occurs on fibrous materials such as cotton waste. Spontaneous
heating of activated carbon is related to the composition and method of
preparation of the activated carbon. Free radicals, present in charcoal, are
responsible for autoignition. Self-heating and autoignition may also result from
adsorption of various vapours and gases (especially oxygen). For example,
activated carbon auto- ignites in flowing air at 452-518 deg. C.; when the base,
triethylene-diamine, is adsorbed on the carbon (5%) the autoignition temperature
is reduced to 230-260 deg. C.. An exotherm is produced at 230-260 deg. C., at
high flow rates of air, although ignition did not occur until 500 deg. C..
Mixtures of sodium borohydride with activated carbons, in air, promote the
oxidation of sodium borohydride, producing a self-heating reaction that may
result in the ignition of charcoal and in the production of hydrogen through
thermal decomposition of the borohydride.
Avoid reaction with oxidizing agents.
