SECTION 3 - HEALTH HAZARD DATA

Routes of Entry:

Inhalation: Unlikely.

Ingestion: Can be fatal if swallowed.

Skin: Skin contact can cause severe chemical burns.

Eyes: Eye contact can cause severe eye damage.

Acute Effects: The electrolyte (potassium hydroxide) is harmful if swallowed, inhaled or absorbed through the skin. It is extremely destructive to tissue of the mucous membranes, stomach, mouth, upper respiratory tract, eyes, and skin.

Chronic Effects: Prolonged exposure with the electrolyte (potassium hydroxide) is destructive to tissue. Chronic exposure to lead can cause blood diseases and cause damage to the kidneys and liver, damage to the reproductive systems and decrease fertility in men and women, and damage the fetus of a pregnant woman. Chronic exposure from the lead contained in this product is extremely unlikely.

Signs and Symptoms of Exposure: Contact of electrolyte (potassium hydroxide) with skin or eyes will cause a burning sensation and/or feel soapy or slippery to touch. Other symptoms of exposure to lead include loss of sleep, loss of appetite, metallic taste, and fatigue. For additional exposure information refer to 29 CFR 1910.1025, Appendix A – Substance Data Sheet for Occupational Exposure to Lead.

Carcinogenicity: Lead is classified by the IARC as a class 2B carcinogen (possibly carcinogenic to humans).

OSHA: If airborne lead exposures exceed the OSHA action level, refer to OSHA Lead Standard 1910.1025.

NTP: N/A

Medical Conditions Generally Aggravated by Exposure: Lead exposure can aggravate blood diseases and blood-forming organs such as hypertension, kidneys, nervous and possibly reproductive systems. Those pre-existing skin disorders or eye problems may be more susceptible to the effects of the electrolyte (potassium hydroxide).

SECTION 4 - EMERGENCY FIRST AID PROCEDURES

Inhalation: Relocate to fresh air and get medical attention immediately.

Skin and Eyes: Immediately flush with copious amounts of water for at least 15 minutes and remove all contaminated clothing. Get medical attention immediately.

Ingestion: Rinse mouth and drink large amounts of water. DO NOT induce vomiting and get medical attention immediately.

SECTION 5 - FIRE HAZARD DATA

Extinguishing Media: Use extinguishing media appropriate to surrounding fire conditions.

Special Fire Fighting Equipment: Wear NIOSH/OSHA approved self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

Fire Protection Classification: B1 (DIN 4102)

SECTION 6 - CLEANUP PROCEDURES

Use a fresh paper towel to wipe down the area several times. Contaminated paper towels are considered hazardous waste.

SECTION 7 - SAFE HANDLING AND USE

Note: The lead anode and potassium hydroxide electrolyte are sealed and under normal circumstances do not present a health hazard. These guidelines are given in the event that an oxygen sensor leaks electrolyte.

Protective Measures During Cell Replacement: Before installing a new oxygen sensor, inspect the polyethylene bag for electrolyte leakage. If the sensor cell leaks, do not open the bag. If there is liquid around the cell while in the instrument, wear eye and hand protection.

SECTION 8 - EXPOSURE CONTROLS AND PERSONAL PROTECTION

Eye Protection: Chemical splash goggles.

Skin Protection: Rubber or Latex gloves. Gloves must be resistant to corrosive materials. Do not use cotton or leather gloves.

Other Protective Clothing: Face shield, Apron.

SECTION 11 - TOXICOLOGICAL INFORMATION

Toxicity to Animals: Acute oral toxicity (LD50): 2730 mg/kg (rat) (Calculated value for the Potassium hydroxide solution).

Mutagenicity: Lead tested positive as a mutagen in the Ames test.

SECTION 12 - ECOLOGICAL INFORMATION

Ecotoxicity: The LC50 of lead for the Daphnia magna is 3.6 mg/l, and 5.1 mg/l for the Daphnia pulex.

Environmental Fate: Lead is bioaccumulative in most aquatic life and mammals. It is highly mobile as lead dust or fume, yet forms complexes with organic material which limits its mobility.
