health harm……….. strong thrill and Corrosive. Catalyze eye and breath. erode
nasal cavity ,skin and eye. Burn if touch, character:
contact cause fat to saponification, come into being
compound of solubility ,then further damaging; suck
cause enteron Burn, mucous membrane rot, bleed and shock.
circumstance harm…………pollution of water. Blast. Apyrous.strong
Corrosive and thrill.burn body.
section 4 FIRST AID MEASURES
4.1 EYES: Immediately flush with large quantities of water for 30 minutes. Hold eyelids apart during irrigation to insure thorough flushing of the entire area of the eye. Obtain immediate medical attention.
4.2 SKIN: Immediately flush with large quantities of water for 30 minutes. Remove contaminated clothing under a safety shower. Obtain immediate medical attention
4.3 INGESTION: DO NOT INDUCE VOMITING. If victim is conscious, immediately give 2 to 4 glasses of water. If vomiting does occur, repeat fluid administration. Obtain immediate medical attention.
4.4 INHALATION: Remove victim from contaminated atmosphere. If breathing is labored, administer oxygen. If breathing has ceased, clear airway and start mouth to mouth resuscitation. If heart has stopped beating, external heart massage should be applied. Obtain immediate medical attention.
Section 5: FIRE FIGHTING MEASURES
5.1 harm character…. Apyrous, strong Corrosive.
Release sulfureted hydrogen( H2S) if reaction with acid.
FLASH POINT: Not flammable METHOD USED: NA
5.2 harmful burning production …………. sulfur dioxide
5.3 Method of extinguishing a fire………. Water, sand earth, foam and carbon dioxide.
5.4 notice of extinguishing a fire …………splash of water and others
cause burn body
Section 6 : ACCIDENTAL RELEASE MEASURES 6.1 Small release: Confine and Absorb small releases on sand earth or other inert absorbent.
Oxidize residual reactive sulfides with a weak(3-5%) hydrogen peroxide solution. 6.2 Large release: Wear proper protective equipment. Confine area to qualified personnel.
Shut off release if safe to do so .Dike spill area to prevent runoff into sewers,
drains(potential explosive mixtures of hydrogen sulfide in confined spaces) or
surface waterways(potential aquatic toxicity). Recover as much of the solution as possible.
Treat remaining material as a small release(above).
Section 7: HANDLING and STORAGE
