control the risks of chemicals

Techniques to control the risks of chemicals:

1 - replacement:

One of the methods to control the risks associated with the use of hazardous materials and techniques. It is replaced by the hazardous materials less hazardous materials, such as replacing the organic base with a glue to glue a water-based
Or replacement of work methods and techniques of hazardous work safer techniques such as replacing the process of mixing paint automatic hand mixer.

2 - Insulation:

Takes the principle of segregation applied mainly through two levels:
- Either to isolate the part that represents a potential danger of the line industrial process such as isolating battery charger in a private room.
- Group or isolate the weak health by putting the work does not make him pollutants.
 3 -wet roads:

An effective method of control to get rid of dust and fibers are harmful to health emanating from some industrial processes through the use of aerosol sprays.

 4 -Ventilation:

It is a way to control chemical contaminants which aims to pull pollutants from the air and provide a continuous source of air Alngiw preferably withdraw contaminated from the nearest place of issue is not to hinder the work.

 5 -personal protective equipment:

It is the last line of defense can be invoked with no possibility of applying the control measures
Leather gloves when contact with hazardous materials - cloth masks to prevent inhalation of fluff material - filtered masks when dealing with gases and volatile substances.
And personal protective equipment is used in cases of emergency Kaltserbat and fires.

Symbols of danger signs and safety

Symbols of danger Risks: (R)

It is a code to indicate the hazards of the chemical symbol and levels of significance
R1 ordnance situation Dry

R10 flammable
R36 cause irritation of the eyes
R204 is proven carcinogenic effects are uncertain

There are dangers of the chemical compound we refer to two digits or more, including a forward slash: R20/21 cause harm when inhaled or by skin
R36/38 Irritating to eyes and skin
R39/26/28. Very toxic: danger of serious irreversible effects if inhaled or swallowed.
Safety Symbols Safety: (S)

It is a code indicating the type and form of warnings and safety requirements: S1 kept closed
S12. Do not save the package closed
S36. Wear appropriate prevention tools
. S62 if swallowed, do not push for action vomiting, and get instructions on the product circulation and get rid of their waste.
S1 / 2 are closed and kept out of reach of children
There are safety warnings of the dangers of the chemical compound we refer to multiple numbers, including a forward slash: S24/25 Beware of contact with eyes and skin
S36/37/39 Wear suitable protective clothing, gloves and raincoats for the face and eyes

Chemical Burn

Chemicals affect the human body burns as a result of their direct impact and not the result of heat and these materials may be in one of the following images:
1) acids: acid Alkipritk - Alklorett acid - nitric acid - acetic acid etc 0000 snow
2) Alkali: Caustic Soda - solution of potassium, ammonia, lime, and ammonia
3) salts: salts of some elements such as mercury - phosphorus - antimony - bromide - Selenium
4) gases: chlorine gas - ammonia
5) remove the colors and powder detergents
Burns and require immediate aid of chemicals, because the passage of time is not in the interest of the patient because it leads to more damage to humans, and water is one of the best means to deal with chemical burns on the condition that the injured part is poured in large quantities as soon as possible
Through our dealings with the chemical laboratory school, both in trading and the storage or preparation for testing or during a students' test prescribed curriculum has become any person due to the followers of safety and occupational health, resulting in burns to the skin or injuries to the eye, which we're making are as follows:

First, chemical skin burns
The injury occurs as a result of direct contact with the human body or exposure to the chemicals mentioned above and most important of which
Acids and alkalis and gases
1) acid:
And divide according to their impact on the human body into two types:
A - acid quick-impact, which caused burns to humans directly in the infected part of the patient as well as the emergence of bubbles or drops in the same part ..
B - acid-impact slow, which does not cause pain to the injured person immediately after exposure to acid, but feel after a period ranging between (1.4 to 1.2 hours) and which are sufficient to penetrate the skin acid to deep space

 2) alkali
Burns resulting from exposure to alkali effect t on humans is greater than that caused by acids because they have a capacity of faster access to the internal tissues and cells of the skin, and the impact of the bad on the tissue remains for a longer period even after washing with water or neutralized chemical treatment, and in this case and after into force of the alkaline solution into
Tissues of the skin, skin is pale and seemed as if saturated with water after going to heal the deep ulceration Ssahy

First aid for chemical burns injury
1 - You must remove the cause of the burn and immediately wash the affected part with running water as soon as possible and must be A, continue the process of washing the affected part with water for at least ten minutes

 2 - You should avoid the use of water under pressure so as not to harm the affected skin, but you must pour water quietly

3 - You should take off clothes in case of patient exposure to chemicals if possible, otherwise you should pour a quantity of
Water or anti-chemical on clothing

4 - the chemical equation must be to mitigate the impact of her on the injured part as follows:
* Burns resulting from exposure to acids, alkalis, weak equivalent status, such as bicarbonate of soda on the affected part

 * Burns resulting from exposure to development of alkali equivalent to weak acids such as acetic acid or light lemon or lime juice (except for eye injury is not used in the eye equivalent) and the solution is also used so-called solution that has a neutral Alphusvi capacity equivalent in acids and alkalis
 
5 - After completion of the equation of the chemical causing the burning of the affected part is washed with water and dried again and connects using a sterile gauze, taking into account not opening until the skin bubbles reduce the area exposed to microbial
 
6 - should aid the patient in the event of exposure to other complications such as pain or shock

7 - to be evacuated after conducting first aid to the hospital if necessary to treat the injured

Chemical eye injuries
Causing chemicals a major impact on the eye in case of infection, so the ambulance correctly and quickly is very important to keep the eye and protect them from damage investigator, especially in the case of injury to Articles alkaline due to its ability to penetrate the tissues of the eye and cause burns deep and severe damage to the
First aid for eye injury in case of chemicals
1 - Wash the affected eye with clean water by placing the patient head under the water tap directly or injured head with water immersion

 2 - The patient should open and close his eye firmly into the water may not be able as a result of pain should be open to the medic for the washing process

 3 - You should not use any chemicals inside the eye of the equation but Alphusvi neutral solution (if any) and may not put any kind of tar or ointments, but the parts are placed on a sterile eye injured and taken to hospital for treatment.
