Health and Safety in Aeration - Essay Example

In the local with pollution "specific " (provoked, that is to say, from the dangerous emission of substances worn or produced during the making), it provides also to eliminate the harmful factors, every time that is technically possible:
- using substitution of the substances polluting with other products except for dangerous;
- Winning polluting him to the source.

To that, it is provided using the installations of ventilation, that they should ensure the dismissal of the polluting remaining, as well as the introduction of the air of compensation and extra for the eventual evacuation to continue of accidents.

In the installation of aspiration, and vice versa, timely they should be treated the positioning of the aspirator to the source, their obstacle, the resonant level and the air of currents of elimination persuaded.

The pollution "I do not specify" of the air can contribute to the onset of modest troubles for the health (shows irritable or allergic to a load of ear equipment), while the pollution "specific" can provoke considerable results for the health (indisposition, asthma, poisoning, actual illnesses from toxic agents inhaled.) that can increase themselves in connection to the duration and to the intensity of the exhibition.

In case of eventual use in the work environments of products polluting (like hydrogen arsenicate, benzene, the brother of metal, the lead) that is in the case in which come carried out intense activities that the scratching, the candidature to jet, the veneer or the painting using pulverization, should be arranged specifically, adequate devices of ventilation of the environments interested or of aspiration to the source.

It had to supply, for the occasion, individual instrumentations of protection fit to confront the abovementioned situations of risk, and to ensure the moderate maintenance of the installations and of the devices, to guarantee a costing level of efficiency.

Identical criteria should adopt themselves also for the installation of air conditioning.

Fire is combustion that is developed in an uncontrolled manner in time and space. Combustion is a chemical reaction between a combustible body and a body comburent. The fuels are numerous: wood, coal, card, oil, combustible gas, etc. The comburent that intervenes in a fire is the air or, more precisely, the present oxygen in the air (21% in volume). The risk of fire, therefore, exists in all the local.

The explosion is combustion to very rapid propagation with violent liberation of energy. It can happen alone in the presence of gas, combustible dust or vapours of some unstable substances and strong reactive or explosive matters.

To anticipate the risk of fire or explosion is necessary to know the actual risks of the enterprise.
