I. Proper use of safety helmets 　　1. Inspect the safety helmet. The main check is to see if there are any cracks or deformations in the cap body ； Check whether the buffer ring inside the cap and the mandibular strap are in good condition, and whether the connections are secure ； Check if it has been struck hard ； Check whether the usage period has expired (the usage period for fiberglass safety helmets is 3.5 years, starting from the date of manufacture) ； Check whether the new safety helmet has the manufacturer’s name, production license number, production date, etc. 　　2. Adjust the size of the cushioning ring inside the safety helmet until there is a slight restraining feeling on the head, but not to an uncomfortable degree; the helmet should not fall off when the head is lowered without using the chin strap ； The vertical distance between the top of the head and the interior of the helmet should be at least 32 millimeters, to ensure sufficient cushioning for the head as well as to facilitate ventilation. 　　3. Wear a proper safety helmet. Do not wear the safety helmet incorrectly; do not put the brim at the back of your head. Female employees must tie their long hair inside a cap. 　　4. Fasten the chin strap. The mandibular strap should fit tightly against the jaw, with a tightness such that there is a sense of restraint but no discomfort. This prevents the safety helmet from being blown away by strong winds, knocked off by other objects, or falling off as the head moves. 　　II. Proper use of air respirators 1. Inspect the air respirator. Check that all components of the air respirator are present and intact, and that the connections between joints, pipelines, and valves are in good condition ； Check the airtightness of the air respirator’s supply system and the pressure level of the air source ； Close the bypass valve and the air supply valve of the air supply unit, then open the bottle valve switch. Put the full-face mask on properly over the head and take a deep breath; the valve of the air supply unit should open automatically to supply air ； Check whether the gas cylinder is securely fixed. 　　2. Wear the air respirator with a quick-connect fitting, with the bottle valve facing downward, on the back of the body ； An air respirator with a quick-connect lower strap: after separating the full-face mask from the air supply valve, the cylinder valve is carried downward on the back of the body ； Adjust the length of the strap according to your height, and adjust the length of the belt according to your waist circumference, then fasten the belt. Adjust the pressure gauge to a position where it is easy for the wearer to view. 　　3. Insert the quick connector properly; the air supply valve and the full-face mask should also be connected properly ； For air respirators without quick connectors, the neck strap of the full-face mask should be worn around the neck. 　　4. Turn the valve on the cylinder by more than one full turn; at this point, a loud alarm sound should be heard, indicating that the cylinder has been filled with compressed air after the valve is opened ； The pointer of the pressure gauge should also indicate the corresponding pressure. 　　5. Put on the full-face mask, take a deep breath. After air is supplied through the supply valve, check the pressure gauge; if there is a drop in pressure, it indicates that the opening degree of the bottle valve is not sufficient, so it should be opened further until the pressure gauge no longer shows a drop. 　　III. Proper Use of Eye and Face Protection Equipment Once appropriate eye and face protection equipment has been selected, it must be used correctly in order to achieve effective protection. Before use, consult the instruction manual to understand the wearing method and precautions, such as whether it is fragile or not. Before wearing it, check whether the protective equipment is in good condition. After putting it on, verify that it is secure and will not fall off when performing work-related actions such as bending or lowering the head. In areas where there is a risk to the eyes, it is essential to wear eye protection at all times. Employees as well as visitors who enter such hazardous areas must comply with the same safety regulations and wear protective gear constantly while on the job site. 　　IV. Proper Use of Protective Equipment for the Auditory Organs 1. When wearing various earplugs, first pull the ear flap upward to flatten the concha of the ear. Then, hold the handle of the earplug and gently push the tip of the earplug into the external auditory canal, making sure that the earplug fits as closely as possible against the concha of the ear. But do not use too much force, be too hasty, or insert it too deeply; it should feel moderate to you. 　　2. If you feel that the sound insulation is not sufficient after wearing them, you can gently move the earplugs slightly to find the position that provides the best performance. If repeated attempts still yield poor results, it is advisable to try different models and specifications of earplugs to find the best one for consistent use. 　　3. When using foam earplugs, replace the cylindrical shape with a conical one before inserting it into the ear canal, allowing the plug to spring back and fill the ear canal. 　　4. When using self-forming silicone rubber earplugs, it is important to distinguish between the left and right plugs and not get them mixed up ； When inserting it into the ear canal, turn it slightly to get it in the correct position so that it fits tightly against the concha. 　　V. Proper wearing of work clothes Properly wearing work clothes helps to regulate body temperature and protect the skin, thereby providing protection against water, fire, toxins, and heat radiation. Whether it is appropriate to wear work clothes is directly related to human health. 　　When working in high-temperature environments, a large amount of heat radiation is encountered; therefore, work clothes worn under such conditions should be made of thick and soft materials as much as possible. Furthermore, when working in high temperatures and sweating a lot, some people prefer to wear no shirt on their upper body; this can lead to heat radiation burning the skin, causing it to become hot and dry, reducing its ability to dissipate heat, and also increasing the risk of injury to the body. Therefore, when working at high temperatures, one should not only wear work clothes but also thicker long-sleeved shirts and pants. 　　VI. Proper wearing of work shoes Choose work shoes of the right size that suit the needs of the workplace. In ordinary places, wear ordinary work shoes ； Wear electric-insulating shoes when working with electricity ； Wear waterproof work shoes when working in areas with water. Make sure to tie your shoelaces tightly; they shouldn’t be too long and dragging on the ground. 　　VII. Proper Use of Safety Belts 1. Select safety belts that are suitable for specific usage scenarios, based on the nature of the industry and the requirements of the job. For tasks such as scaffolding work, painting, and welding, suspension safety belts should be used, while electricians should use guardrail safety belts. 　　2. Before use, check the seat belt for the following issues: any signs of damage on the surface ； Are all the components of the seat belt in good condition? ； Check whether it has exceeded its service life; the service life of a seat belt is 3–5 years, and it should be retired in advance if any abnormalities are detected. It should be noted that after two years of use, the seat belt must be inspected randomly ； Does the new seat belt have the manufacturer’s name, production license number, production date, etc.? 　　3. The safety belt should be worn high and low, and it is strictly prohibited to wear it low and high. 　　4. The safety belt must be attached to a secure and reliable location; it must not be used with knots, nor should the hook be attached directly to the safety rope – the hook must be used by attaching it to the connecting ring.
