ABC powder fire extinguisher mechanism of chemical inhibition, blocking the chain reaction of combustion, fire fighting high-level, full-featured, quickly extinguishing electrical insulation properties and good low temperature performance, especially suitable for use in factories and enterprises, warehousing and outdoor configuration . Inadequacies that: powder extinguishing agent is not anti resurgence, fire extinguishing an oil fire fighting level (B class fire), the user will be required to go through specialized technical training; powder fire extinguisher in use, especially in indoor use, stimulate the respiratory tract; fine dust filled the entire space, the use of dry powder fire extinguishers in the buildings, causing serious secondary pollution. Carbon dioxide fire extinguisher mechanism of suffocation by lowering the ambient air oxygen concentration of the combustion products to the implementation of fire. Carbon dioxide as the extinguishing agent, insulating properties, especially suitable for the vault, Documentation Archive does not allow any pollution and loss of places after the fire. However, its inadequacies: the high concentration of fire, so the fire extinguishing low level, should be used in a relatively confined space; difference anti resurgence ability; carbon dioxide is a moderately toxic material, when the carbon dioxide concentration in the air to reach 2% when, can lead to unpleasant sense. When the concentration of 7-9%, it will cause difficulty in breathing, vomiting, numbness, mental confusion. When the concentration reaches 10%, the person stays in the environment for a minute, will lose consciousness. When using a carbon dioxide fire extinguisher, its local concentration is much higher than the concentration. Day-to-day fire safety measures: 1, before work, turn off all switches total gate (sewing machines, fluorescent tubes, machines, hot bed, iron, doors, windows, etc.); 2, regularly blowing the motor of the sewing machine; 3, the smell of charred the the odor immediately stoppages check total gate closed and notify electricians and office; not allowed random access wire, electric seat; 5, weekly check fire facilities (fire extinguishers, hydrants, pumps, pool); 6, to keep the channel smooth, fire extinguisher near or place debris; 7 of concentrated hydrochloric acid cleaning may not be used for washing, washing equipment, highly volatile combustion is water that day; 8 is strictly prohibited in the area of ??the factory fire, light candles, smoking; 9 welding plant in the region to ensure that no flammable materials nearby, and a fire extinguisher after the completion of check nearby welding feces; 10, may not take the elevator with flammable substances; 11 not mess with indiscriminate spraying fire extinguishers. II factory fire emergency measure: 1, pull down the gates (engine); 2, take the fire extinguisher in the vicinity immediately put out, pressing the fire sprinkler; 3, turn on the alarm system, and 119 fire call; 4 organizations evacuation of employees, called on workers not to panic and onlookers; commanding staff their noses with a damp cloth to prevent choking injuries; 6 fire may not go to the elevator.
