Emergency treatment of specific methods
1.Assistance should wear appropriate personal protective equipment safety , in order to ensure their own safety.
2.Remove the victim to fresh sources of pollution or air circulation .
3.If breathing stops, give artificial respiration by trained personnel and cardiopulmonary resuscitation . Avoid contact with mouth to mouth , preferably under the guidance of a doctor oxygen .
Skin contact : Avoid direct contact with the chemical , if necessary, wear impervious gloves. (2) Immediately Hexafluorine (PREVORHEXAFLUORINE Solution) Rinse the affected area . And flushing while removing contaminated clothing and avoid chemicals through clothing to expand the area of contact with the body . 3 If the scene was not Hexafluorine (PREVOR HEXAFLUORINE Solution), immediately wash the affected area with warm water to ease the flow of more than 15 minutes . And when flushing while removing contaminated clothing. Then apply the injury at 2.5% calcium gluconate gel . 3 hospital .
Eye contact :
1.Immediately Hexafluorine eyewash (PREVOR HEXAFLUORINE Solution, LPM 500ml) flush eyes recommends disposable after use . Then osmotic balance eye lotion (AfterwassII, 200ml) wash your eyes , wash splashes and ease the discomfort produced .
2.If the scene did not Hexafluorine (PREVOR HEXAFLUORINE Solution), immediately lift eyelids , with running warm water to rinse the affected area for 15 minutes. Be careful not to rinse contaminated with uncontaminated eye. If you can not immediately seek medical treatment , you can drop one or two drops of 0.5% tetracaine hydrochloride solution (Pontocaine), then seek medical advice. 3 hospital .
1.If the patient is about to lose consciousness , has lost consciousness or convulsions , do not feed anything by mouth .
2.gargle thoroughly with cold water .
3.Do not induce vomiting.
4.Let the patient drink 240-300ml of 10% calcium gluconate solution to dilute stomach substances.
5.If the patient spontaneously vomiting, the patient body forward in order to avoid inhaling vomit .
6.repeatedly to patients to drink water.
