The unit’s gas protection equipment
Thread Content
Dear sea friends, does your unit have gas protection equipment? If so, how can regular checks be performed to determine its availability? Will all employees of the organization use it?
In our organization, the main party responsible for inspections is the using department (manufacturing), and the management in this area is not very good
Larger companies tend to perform better, while smaller companies may not do as well. Protective equipment against toxins is generally available, but maintaining and using it can be a challenge....
Every unit should be equipped with this; our workshop has two sets of positive-pressure respirators and 4 sets of gas filters. This kind of thing seems useless when you look at it on a daily basis, but only when an accident occurs do people remember it – only to find that they don’t know how to use it. Moreover, many accidents are not caused by the device itself, but rather by improper use of it. Therefore, we need to carry out training in this area from time to time. It’s not some high-tech thing either; it’s something that can be learned easily. Yet many people still refuse to learn, mainly due to a sense of luck in their mindset.
Incidentally, modern positive-pressure respirators are made of carbon fiber, making them lightweight and easy to use； There is usually a fixed testing schedule, with tests conducted once a year, and professional testing institutions are available for this purpose ； It is also necessary to regularly check whether there is oxygen in the bottle and whether the oxygen pressure is normal. During the inspection, wear the breathing mask, open the cylinder valve, and check whether the pressure on the gauge rises.
It is recommended not to use oxygen-powered positive-pressure respirators, as they are not suitable for areas with fire hazards; using compressed air-powered positive-pressure respirators would be safer.
If your company is willing to invest in safety, then air respirators will be available. Require front-line employees to be proficient in using it
Our office has anti-blocking masks, but few people use them! Moreover, in normal operations, even during hydrocracking at 4.0 Mpa where hydrogen sulfide is present, workers are not provided with respirators. We just eat eggs all day like this!
Our company has them; the more common ones are used by everyone, while only a few people use the more specialized ones, mainly those in the safety and emergency response team. The company organizes training on related knowledge every year
Gas masks need to be checked regularly. The paint used is the kind that contains activated carbon; if the activated carbon stops working, accidents can occur
In our chlorine-related work areas, each employee is equipped with a filter-type gas mask; these masks are provided to each person on a quarterly basis. Every workstation is fitted with air respirators, and the company also provides long-range respirators for use when entering towers and tanks.
Each of us is equipped with a gas mask, and there is an additional one in the emergency relief cabinet for every 4 people. Positions involving chlorine are equipped with positive-pressure air respirators. All relief equipment is checked once a week to ensure it is in working order.
By regulation, gas protection equipment must be available, but whether it is actually used and properly maintained is another matter; it depends on the level of attention given to this aspect by the organization. If relevant systems can be established, with dedicated personnel assigned to regularly inspect and maintain such equipment, and if several practical drills are organized each year, then this issue can be properly addressed
Gas protection equipment is generally divided into filtering type and supply-type; it is difficult to determine the appropriate time for replacement for filtering type equipment, and a comprehensive assessment based on the usage environment and duration of use is required； Air-supplied devices, such as SCBA, require regular inspection to check the air pressure, the airtightness of the tubing, and whether the alarm whistle is in good condition.
