SECTION 3 - HAZARDS IDENTIFICATION

 

Major Health Hazards: The onset of symptoms varies depending upon such factors as the route of absorption and quantity involved. In patients with occupational poisoning, skin symptoms usually develop within 4-6 hours after exposure, with systemic symptoms occurring as late as 48 hours after exposure. Paraesthesia of the facial skin can develop approximately 30 minutes after exposure and does not usually last beyond 24 hours when exposure is terminated. Following ingestion, the initial symptoms involve the gastrointestinal tract, developing 10-60 minutes after exposure. Patients suffering from acute oral poisoning usually develop prominent digestive symptoms such as epigastric pain, nausea and vomiting. Severely poisoned patients may have frequent convulsive attacks, coma, or pulmonary oedema. The prognosis is good if treated, with usually full recovery even in severely poisoned patients. (The hospitalization period is usually longer than 4 weeks).

 

SECTION 4 - HAZARDS IDENTIFICATION

 

General Information:


 

 

You should call The Poisons Information Center if you feel that you may have been poisoned, burned or irritated by this product. Have this MSDS with you when you call.

 

Inhalation: If vapors or mists have been inhaled, and irritation or unusual symptoms have developed, remove to fresh air and observe until recovered. If irritation or symptoms persists more than about 30 minutes, seek medical advice.

 

Skin Contact: If product gets on skin, immediately remove contaminated clothing and wash skin thoroughly with soap and water to remove material. If you begin to feel unwell, seek medical attention.

 

Eye Contact: If product gets in eyes, wash material from them with running water. If they begin watering or reddening, take special care in washing thoroughly.

 

Ingestion: If swallowed, do NOT induce vomiting. Wash mouth with water and contact a Poisons Information Center, or call a doctor.

 

Advice to Doctor: Treat symptomatically. Note the nature of this product.

 

SECTION 5 - FIRE FIGHTING MEASURES

 

Extinguishing Media: carbon dioxide, dry chemical, foam, and water fog.

 

Special Fire fighting procedures: If a significant quantity of this product is involved in a fire, call the fire brigade. When fighting fires involving significant quantities of this product, wear safety boots, non-flammable overalls, gloves, hat, goggles and respirator. All skin areas should be covered.

 

Unusual Fire & Explosion Hazards: Fire decomposition products from this product may form toxic mixtures in confined spaces. Vapors from this product are heavier than air and may accumulate in sumps, pits and other low-lying spaces, forming potentially explosive mixtures. They may also flash back considerable distances.

 

Stability: This product is unlikely to spontaneously decompose.

 

Fire Decomposition: Carbon dioxide, and if combustion is incomplete, carbon monoxide and smoke. Water. Carbon monoxide poisoning produces headache, weakness, nausea, dizziness, confusion, dimness of vision, disturbance of judgment, and unconsciousness followed by coma and death

 

SECTION 6 - ACCIDENTAL RELEASE MEASURES

 

Avoid contact with the spilled material or contaminated surfaces. Do not smoke, eat or drink during the cleanup process. Personnel involved in cleanup should wear full body protective


 

 

clothing and equipment as described in Section 8 – PERSONAL PROTECTION.

 

Keep people and animals away. Consider evacuation and obtain assistance from emergency services if needed. Prevent spilled material from entering drains or watercourses.

 

Contain spill and sweep up carefully. Avoid creating dust. Collect and store in recovery drums.

 

Clean floor with detergent and water, absorbing wash water with clay granules and transfer this to the drum. Seal and label drums for safe disposal. Deal with all spillages immediately. If contamination of drains, streams, watercourses, etc. is unavoidable, warn the local water authority.

 

Decontaminate tools, equipment and clothing used in the cleanup. Dispose of any heavily soiledclothing, placing it in disposal drum.

 

SECTION 7 - HANDING AND STORAGE

 

Store in cool, clean, ventilated, fireproof storage area. Keep away from heat, spark, open flame and incompatible materials. (Strong oxidizing agents). Protect containers against physical damage.

 

SECTION 8 - EXPOSURE CONTROLS, PERSONAL, PROTECTION

 

Exposure Standards:

 

A time weighted average (TWA) concentration for an 8-hour day, there is a blanket limit of 10mg/m3 for dusts or mists when limits have not otherwise been established. The nature of this product makes it unlikely that this level will be approached in normal use. The ADI (Acceptable Daily Intake) for Cypermethrin is set at 0.05 mg/kg/day. The corresponding NOEL (No- observable-effect-level) is set at 5 mg/kg/day.

 

Engineering Controls:

 

In industrial situations, concentration values below the TWA value should be maintained. Values may be reduced by process modification, use of local exhaust ventilation, capturing substances at the source, or other methods. If you believe air borne concentrations of mists, dusts or vapours are high; you are advised to modify the process or environment to reduce the problem.

 

Personal Protection:

 

Respiratory Protection : If there is a significant chance of dusts, vapours or mists accumulating in the area where this product is being used, a mask or respirator should be used. For help in selecting suitable equipment.

 

Protective Gloves : Impermeable elbow length PVC gloves should be worn when you are using this product, since absorption through the skin is harmful. For help in selecting suitable equipment.

 

Eye Protection : Protective eyewear is suggested when using this product. It is always prudent to use protective eyewear.

 

Clothing : Clean overalls or protective clothing should be worn, preferably with an apron.

 

Safety Boots : Wearing safety boots in industrial situations is advisory.

 

Always wash hands before smoking, eating or using the toilet. Wash contaminated clothing and other protective equipment before storing or re-using.
