Long-term work in an environment with dust or toxic gases can cause damage to the human respiratory system if appropriate protective products such as papr respirator for healthcare are not used. The damage to the lung organs and tissues is usually very serious and irrecoverable. The finer the dust, the easier it is to enter the end of the bronchi, and the greater the killing power.
I. Types of respiratory hazards
Tiny solid particles suspended in the air. Generally produced by large solid materials broken by mechanical force, or produced in the transport of powder, such as ore crushing, metal grinding, sweeping, material cutting and mixing of powder and other processes.
The tiny solid particles suspended in the air. Usually tiny particles condensed by substances burning and vaporizing at high temperatures and then cooling. The most common is the metal produced in the welding and casting process.
Tiny liquid particles suspended in the air. Usually produced by liquid spraying or vapor condensation, such as paint spraying process produces paint fog, some acid liquids also tend to form acid fog, such as sulfuric acid. Many fogs are also volatile and produce vapors.
A variety of bacteria, germs, mold, toxins, spores and other organisms present in the air. Many of them are contagious, generally attached to other particles in the air spread, can enter the human body through the respiratory tract
Substances that exist in gas form at room temperature and pressure. Such as chlorine, carbon monoxide, hydrogen sulfide and sulfur dioxide, ammonia, etc. Some have a distinct odor, some have irritation, but there are also colorless and tasteless.
6、Filtered respiratory protection
Refers to the filter media such as filter cotton, filter box, the air in the surrounding environment of dust, gas and other harmful substances filtered to provide the user with clean air to breathe. Breathing air from the air in the surrounding environment. For example: protective masks, gas masks, papr respirator for healthcare.
7、Insulated respiratory protection
Refers to the breathing does not depend on the air in the surrounding environment, breathing air from the air source outside the work environment.
The papr respirator for healthcare uses a blower to provide a steady, cool and purified flow of air, usually worn around the user's waist. Ambient air is drawn into the respirator, filtered through multiple filters and then supplied to the user through a breathing tube. This battery-powered respirator is ideal for long-term use, such as for sewage disposal, disinfection or welding work in hot environments.
The papr respirator for healthcare can be used with a hood or helmet as a full or half face hood. Also known as a gas-supplied respirator or air-supplied respirator, the air tube respirator is connected to a compressed air source (such as an air tanker or stationary air supply unit) through a high-pressure hose. Air can be continuously or intermittently delivered in sufficient quantity to the person with such a device to meet the breathing needs.
