RESPIRATORY HEALTH PROTECTION

RESPIRATORY PROTECTION:

RISK MANAGEMENT AND SECURITY EQUIPMENT

Respiratory risk management is essential in work environments where exposure to harmful and toxic substances can have serious consequences for human health. Respiratory protection devices, classified as Category III Personal Protective Equipment (PPE), play a crucial role in preventing high risks, including possible fatal situations, resulting from contamination of the respiratory system.

PROTECTIVE EQUIPMENT FOR THE RESPIRATORY TRACT

In various activities where respiratory conditions are abnormal and there is a significant health risk, it is essential to use appropriate respiratory protective equipment. The choice of device should be based on air conditions, including the amount of oxygen and contaminants present.

AIR COMPOSITION AND PROTECTIVE EQUIPMENT FOR THE RESPIRATORY TRACT

Respiratory Risk - Oxygen Content (O2) Greater than 17% FILTERING DEVICES These devices are effective in filtering air contaminated by gases, vapors, dusts, fumes and mists. Its use is recommended when the nature and concentration of the contaminants in the air are known, and when their odor is perceptible.

FILTERING ANTI-DUST SEMI-MASKS (EN 149)

SEMI-MASKS AND FOUR MASKS (EN 140)

FULL MASKS (EN 136)

DUST FILTERS (EN 143)

ANTI-GAS FILTERS AND COMBINED FILTERS (EN 14387)

Respiratory Risk - Oxygen Content (O2) Less than 17%

INSULATING RESPIRATORS

These devices isolate the user from contaminated air by providing clean air from an outside source to the contaminated environment or through compressed air in bottles. Its use is recommended when the nature and concentration of the contaminants is not known, when the odor is not perceptible and when non-filterable substances are present.

TLV AND CLASSIFICATION OF CONTAMINANTS

The Threshold Limit Value (TLV) indicates the safe concentration limits of hazardous substances to which a worker can be exposed without suffering damage to health throughout a work shift. If the concentration of toxic contaminants in the air exceeds the TLV, it is essential to use a respiratory protection device.

Various types of contaminants harmful to human health are identified, including: Dust: solid particles suspended in the air, generated by processes such as milling, grinding, sanding and sandblasting. Fumes: solid particles resulting from vaporization and condensation in casting, welding and flame cutting processes.

Mist: small liquid droplets generated by atomization processes, present in activities such as plating, mixing or production of metal powders.

Gases: Substances similar to air in terms of diffusion, such as carbon monoxide, carbon dioxide, nitrogen, and helium.

Vapors: gaseous state of substances that are normally in a solid or liquid state, produced by the evaporation of solids or liquids, such as petroleum vapor, diluents and solvents.
