Long tube breathing apparatus
Daniel Lee Silver, anti-chemical study of Chinese text hospital
Long tube respirators, long tube of the mask, also known as air-supplied respirator, a wearer of the respiratory organs and the surrounding exposure environment isolation, relying on the wearer's breathing force or by mechanical force by the inspiratory hose into clean air respiratory protective equipment, for a long time in the anoxic, full of toxic and hazardous gases, steam, harmful aerosol environment Placement operations or liquidity small range of jobs.
Species
Long tube breathing apparatus in general by the mask, strap and gas supply system. According to the working principle, the long tube divided into two kinds of clean air input and pressure-gas respirator. Clean air input type is divided into three kinds of self-suction and air type of two kinds; pressuring gas into the constant current supply - demand gas and compound gas type, are shown in Table 1.
Use
When using a long tube breathing apparatus, one should pay attention to the placement of air quality and the suction hose to prevent the inspiratory hose killed angle phenomenon in order to avoid supply interruption, so that the suffocation of the wearer, the risk of casualties; should pay attention to check the suction hose connector is securely connected to prevent the joints in the use of drag and fall off, resulting in poisoning injury or death; should pay attention to check the long pipe is ruptured.
Face mask
Long tube respirator mask seal type, non-sealing face mask and air supply hood. Seal face mask should fit the face or head of the body's good, no obvious tenderness. Nengzhe open mask should cover the eyes, nose and mouth, does not affect the head and body movements, airflow at the entrance to set the shunt device without exhalation valve. Eye window of the mask should be used colorless transparent material, the light transmittance of not less than 85% visual clarity without distortion, with Paul out measures, should have sufficient flexibility and strength of the fixation system, easy to swap parts. Air hood should be able to cover the head, eyes, nose, mouth, neck (can be used in conjunction with protective clothing), does not affect the head, body movements, airflow at the entrance to a shunt device; set exhalation valve for the seal type.
Long suction tube respirator
Long suction tube respirator full face mask, strap, suction hose, the air inlet (or filter) and the bracket (or warning board). This respirator is the airway inlet side away from the polluted environment of toxic and hazardous gases, fixed in a fresh and clean place to the other side with full face mask connected to rely on the wearer's breathing force as the driving force will be clean inhalation mask breathing zone for the breathing air through the breathing hose, personnel exhaled gases discharged into the ambient atmosphere through the exhaust valve. Should be set at the entrance to the air to prevent harmful substances into the low-resistance filter. This is a negative pressure respirator, and the requirements of the mask and connected systems have a good air tightness, inspiratory hose length should not exceed 10m, applies to the unlikely place of toxicants. One of the disadvantages of self-suction ventilator inspiratory resistance and inspiratory resistance increases with the increase of the suction hose length; fuzzy eye window lens can easily be exhaled water vapor, resulting in blurred affect the operation.
Air type respirator
Air type respirator by the composition of the mask, with a fixed flow regulator, suction hose, filter and blower, etc., can be divided into two kinds of electric air and manual air according to the source of momentum. This respirator air supply can be adjusted according to user requirements, breathing a little resistance, can form a slight positive pressure within the mask to prevent the leakage of harmful gas into the mask, wearing comfort and safety. Emergency situations, regardless of the blower is working, should be able to guarantee the wearer breathing. The characteristics of the powered air respirator without restriction of the use of time, gas volume, the same time for 1 to 5, air volume according to the length of the number and the suction hose. Electric blower sub-explosion-proof and non-explosion-proof two kinds of non-explosion-proof electric blower can not be used for methane gas, liquefied petroleum gas and other combustible gas concentrations close to or more than the place of the explosion limit. Manual air-contained breathing apparatus without an external power supply, air supply blower rpm.
Pressure gas-contained breathing apparatus
The compressed air breathing apparatus air compressor or high pressure air bottle by the pressure regulating device pressure reduced in pressure, then the gas through the inspiratory hose to the mask for the wearer to breathe, the surplus gas and exhaled gas discharged into the ambient atmosphere through the exhaust valve.
Constant current supply-contained breathing apparatus
The composition of the constant current supplied-air respirator masks, suction hose, flow control device, belts, filters, oil water separators and compressed gas source, the compressed air as the gas source, after breathing hoses and flow regulation device continuously to provide breathable air to the wearer applies to hypoxia and immediate danger to human safety and health (ie non-IDLH) environment. The use of this respirator to deal with compressed air purification, remove the oil and water to ensure the cleaning of the gas source, not hypoxia.
Demand supplied-air respirator
Demand supplied-air respirator mask, for valves, connectors, strap, suction hose and compressed air source and other components. The characteristics of this respirator is used for the valve, according to the needs of the wearer to adjust the gas supply. Depending on the type of supply valve can be divided into positive pressure and negative pressure type two kinds; depending on the type of gas source can be divided into two kinds of mobile and fixed.
Mobile long tube breathing apparatus
Mobile long tube and into a group using breathing apparatus consists of a number of high pressure cylinders, mounted on a movable cart, through the longer aspirated hose for the wearer. This respirator for a long time, the workload of complex work in a wide range of chemical, biological pollution of the environment. Its source of supply is generally from 2 to 6 volume 6L ~ 12L, rated working pressure of 30MPa the composition of the composite cylinders, alarm, gas hose, pressure gauge and trolleys are available for one or more persons to use. Use more than 2 people, should all wear a good respirator with access, and to keep the distance and direction to prevent interact traction for the trachea and unexpected.
Complex gas-contained breathing apparatus
Composite supplied-air respirator with a 2-way supply air source, all the way through the inspiratory long tube gas, another way for users to carry a small high-pressure cylinders. This respirator has a relatively high use of reliability, long pipe gas supply failure occurs due to some reason, you can immediately change from a small cylinder gas supply to ensure the safety of the user's life.
Select
Long tube contained breathing apparatus should be considered the nature of the hazardous chemicals, workplace contaminants may reach the highest concentration of the oxygen content of the workplace, the user's face, and environmental conditions and other factors. Wear is needed before a certain amount of professional training in order to ensure the safe use of the choice of structure is more complex long tube respirator.| Updated:2012.02.03 Source: Clicks:1568
