4 - First Aid Measures

---

AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician immediately.

5 - Fire Fighting Measures

---

EXTINGUISHING MEDIA
Suitable: Water spray. Carbon dioxide, dry chemical powder, or
appropriate foam.
SPECIAL RISKS
Specific Hazard(s): Emits toxic fumes under fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.

---

6 - Accidental Release Measures

---

PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP

7 - Handling and Storage

---

HANDLING
Directions for Safe Handling: Do not get in eyes, on skin, on
clothing. Do not breathe vapor. Avoid prolonged or repeated
exposure.
STORAGE
Conditions of Storage: Keep tightly closed.

---

8 - Exposure Controls / Personal Protection

---

ENGINEERING CONTROLS
Safety shower and eye bath. Use only in a chemical fume hood.
GENERAL HYGIENE MEASURES
Wash contaminated clothing before reuse. Wash thoroughly after
handling.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory Protection: Use respirators and components tested and
approved under appropriate government standards such as NIOSH (US)
or CEN (EU). Where risk assessment shows air-purifying respirators
are appropriate use a full-face respirator with multi-purpose
combination (US) or type ABEK (EN 14387) respirator cartridges as
a backup to engineering controls. If the respirator is the sole
means of protection, use a full-face supplied air respirator.
Hand Protection: Compatible chemical-resistant gloves.
Eye Protection: Chemical safety goggles.

SIGNS AND SYMPTOMS OF EXPOSURE
To the best of our knowledge, the chemical, physical, and
toxicological properties have not been thoroughly investigated.
In contrast to inorganic mercury compounds, alkyl mercury
compounds rapidly pass through the placenta and blood brain
barrier. The peripheral and central nervous systems and the
kidney are major target organs. Methylmercury poisoning symptoms
result primarily from damage to the nervous system. The symptoms
are primarily characterized by loss of sensation in the hands
and feet and in areas around the mouth, diminution of vision
resulting in tunnel vision, ataxia, dysarthria, and hearing
loss. Severe poisoning produces blindness, coma and death. There
is a latent period of weeks to months before development of the
poisoning symptoms. Mercury shows a specificity to damage small
nerve cells in the cerebellum and visual cortex. Methylmercury
causes degeneration and necrosis of neurons in the focal areas
of the cerebral cortex, especially within the visual areas of
the occipital cortex and the granular layer of the cerebellum.
It has been found that methylmercury inhibits protein synthesis
in the brain before symptoms of poisoning appear and that

recovery of protein synthesis does not occur in granular cells
as it does recover in other neuronal cell types. Consumption by
pregnant women has caused serious neurological disorders in
their offspring resulting in mental retardation with cerebral
palsy. Acute exposure to nonlethal levels of methylmercyry
results in
ROUTE OF EXPOSURE
Skin Contact: Causes skin irritation.
Skin Absorption: Readily absorbed through skin. May be fatal if
absorbed through skin.
Eye Contact: Causes eye irritation.
Inhalation: Material is irritating to mucous membranes and upper
respiratory tract. May be fatal if inhaled.
Ingestion: May be fatal if swallowed.
TARGET ORGAN INFORMATION
Kidneys. Nerves.
CONDITIONS AGGRAVATED BY EXPOSURE
May cause nervous system disturbances.
