Впрыскивание (инъекция)
По принципу укола, который вам делает врач во время болезни, химические вещества могут попасть в ваш организм. Если вы работаете рядом с оборудованием под высоким давлением – например, системами сжатого воздуха, шприцами для густой смазки, гидравлическими системами, - существует потенциальная опасность такого рода происшествия. Будьте предельно внимательны, находясь рядом с любым оборудованием с системами под высоким давлением или впрыском. Ни в коем случае не используйте сжатый воздух для чистки рук и одежды.
How Chemicals Enter Your Body
In order for a chemical to have an affect on you, you have to come in contact with a chemical in its solid, liquid or gas form.
There are four "routes of entry" or paths a chemical can take.
Breathing (inhalation)
Chemicals can enter through your lungs as you breath the air around you, some chemicals can irritate your lungs, nose and throat, like ammonia. Others can be absorbed into your blood, travelling to and affecting the organs in your body. Prolonged exposure to Hazardous Substances like asbestos and other solid fiber materials can causes serious health problems. Dusts and fibers can become trapped in your lungs causing irritation, scarring and damage.
Regardless of the type of chemical you work with, your first line of defense against breathing in hazardous chemicals is to use an approved respirator.
Through Your Skin (absorption)
Although the skin is a very effective barrier to most chemicals, it can be penetrated. Damaged to the skin from cuts, scrapes, cracking, dryness or other conditions can allow a chemical to enter into the body. Some chemicals can damage the skin on contact and others pass through the skin and into your bloodstream. A group of chemical solvents such as toluene, gasoline and mineral spirits are absorbed easily through your skin. Some pesticides like parathion can easily pass through the skin, a building up to poisonous levels in the body.
There are two easy steps which will prevent absorption - wearing gloves that are chemical resistant and washing off any chemical that contacts the skin as soon as possible. When you're washing, make sure you use a product designed for washing skin and not product like paint thinner, turpentine and benzene.
