Basic first aid in the chemical laboratory




________________ do not often happen in well-equipped chemistry laboratories if students understand safe laboratory procedures and are careful in following them. When an occasional accident does occur, it is likely to be a minor one. The following information will be helpful to you if an accident occurs.

If something happens, notify the teacher immediately! An accident report must be filled out.

You should know the location of the first aid kitin the ________________.

1) Chemicals in the Eyes

Getting any kind of a chemical into the eyes is undesirable, but certain ________________ are especially harmful. They can destroy eyesight in a very short time. Because you will be wearing ________________ or goggles in the lab, the likelihood of this kind of accident is remote.

However, if it does happen, remove contact lenses and flush your eyes with water in the eye washimmediately. It is important that flushing with water be continued for a prolonged time - l0 or 15 minutes. While flushing is continuing, the nurse should be informed.

2) Chemicals in the Mouth

The likelihood of this kind of accident is unlikely. However, if it does happen, any chemical taken into the mouth should be spat out and the mouth rinsed thoroughly with water. Many chemicals are ________________ to varying degrees. Note the name of the chemical and notify the teacher immediately. If the victim swallows a chemical, note the name of the chemical and notify the teacher immediately. If necessary, the teacher will address to a ________________ for instructions.

3) Chemical Spills on the Skin

For a small area, flush the skin with water first. For a small acid or base spill on the skin, neutralize an acid with baking soda; neutralize a base with boric acid. For a large amount of chemical slipped on the body, use the safety shower. Take the ________________ to the nurse.

4) Fire - Clothing or Hair

A person whose clothing or hair catches on fire will often run around hysterically in an unsuccessful effort to get away from the fire. This only provides the fire with more oxygen and makes it burn faster. It is the responsibility of the teacher or the closest person to bring the fire blanketto the victim as quickly as possible. Smother the fire by wrapping the victim in the blanket. Tell them ―Stop, Drop and Roll! Notify the office clinic immediately.

5) Bleeding from a Cut

Most cuts that occur in the chemistry laboratory are minor. For minor cuts, apply pressure to the wound with sterile gauze, wash with soap and water, and apply a sterile bandage.

If the victim is ________________ badly, raise the bleeding part, if possible, and apply pressure to the wound with a piece of sterile gauze.

6) Fainting

If a person faints, lie the person down on the back. Position the head lower than the legs and provide fresh air. Loosen restrictive clothing.

7) Shock

People who are suffering from any severe injury (for example, a bad burn or major loss of blood) may be in a state of shock. A person in shock is usually pale and faint. The person may be sweating, with cold, moist skin and a weak, rapid pulse. Shock is a serious medical condition. Do not allow a person in shock to walk anywhere. While emergency help is being summoned, place the victim face up in a horizontal position, with the feet raised about 12 inches. Loosen any tightly fitting clothing and keep him or her warm.

Consider these rules ________________, but still consider that it’s better both for you and for your group mates and teachers to follow the safety rules in order to avoid any possible risks.
