Safety helmet use common sense

1 , safety helmet

Germany Schubert F220 fire helmet

Safety helmet refers to a hat that protects the human body from external forces and is composed of a cap shell, a cap liner, a lower jaw strap, and a rear hoop.

2 , technical performance requirements

Safety helmets mainly act as cushioning shock absorbers and disperse impact forces. Therefore, safety helmets should have the following technical performance requirements:

a. Basic technical performance requirements: including impact absorption and puncture resistance.

b. Special technical performance requirements: including electrical insulation, flame retardancy, lateral stiffness, and antistatic properties.

3 , classification

Safety helmets are categorized according to the material and shape of the workplace:

a. Classification by materials: engineering plastics, rubber materials, paper compounds, plant materials; materials for cold-proof caps; materials for cap liners, cap linings, and material for top straps and sewers   With materials.

b. Classified by shape: no edge, small edge, curl edge, middle edge, large edge and so on.

c. Classification by site: General operations and special operations.

4 , purchase and storage

a. Purchasing: The company must purchase the product of the inspection certificate of the oil product. After the experience of the purchased product is collected, it must be used.

b. Storage: Safety helmets should not be stored in places such as acids, alkalis, high temperatures, sunlight, and humidity, and they should not be placed together with hard objects.

5 , the use of safety helmets: calculated from the date of completion of product manufacturing.

a. Plant weave caps not more than 2 years

b. Plastic caps, paper glue caps do not exceed 2 and a half years

Fiberglass (vinylon steel) rubber caps do not exceed three and a half years.

Enterprise security technology sector should be carried out in accordance with the provisions of the expired checks safety helmet testing, qualified only after continued use; once a year after random testing, random testing is not   If qualified, the batch of safety helmets will be scrapped.

6 , signs and packaging

Each safety helmet should have the following 4 permanent signs:

a. Manufacturer's name, trademark, model number

b. Manufacturing year, month, day

c. Production certification and verification

d. Production license number.

7 , safety helmet selection and precautions

a. Selection principles

1 People who work in parabolic or flying objects from high altitude (or on the side), high altitude workers, and those who need to enter such sites are all   Must wear a safety helmet.

2 Selection of materials: The main consideration is to accept the mechanical strength and working environment. If it is estimated that the weight of falling objects is large, it should be made of higher strength materials.   Safety helmets; safety helmets for high temperature resistant glass steel should be used in smelting workplaces; bamboo helmets should be used for ventilation and heat dissipation in building construction in hot areas;   In cold areas, outdoor operations should use cold-proof safety helmets.

3 Selection of styles: Dayan (tongue) caps are suitable for open-air operations, and have the effect of preventing sunlight and rain; small rims are suitable for indoor, tunnels, culverts, wells   There is a narrow range of activities such as lanes, forests, scaffolding, and other activities that are prone to brim collisions.

The choice of 3 colors: should be considered from the perspective of security psychology. Internationally more common practice is: yellow plus black stripes is a sign of caution   Red is a sign that limits or prohibits; Generally for the safety helmet used by ordinary trades should choose white, light yellow, light green and other colors;   Coal mine miners should use bright colors, and even consider putting fluorescent strips or reflective tapes on safety helmets, so that they can easily be made in poor lighting conditions in the workplace.   It is also alert; in the forest cutting area, red and orange safety helmets are eye-catching and easy to find each other; inflammable and explosive workplaces should use red safety helmets.   . Some companies use safety helmets of different colors to distinguish between job titles and job types to facilitate production management.

b. Use caution

1 Before wearing a safety helmet, check that all components are complete and in good condition before use.

2 Workers wearing high-altitude helmets should fasten their armpit straps and back caps to prevent the caps from slipping and being knocked off.

3 Thermoplastic safety helmets can be rinsed with clean water, must not be soaked with hot water, and must not be baked with radiators or stoves to prevent deformation of the cap body.

4 Strictly enforce the regulations concerning the service life of safety helmets, and must not use scrapped safety helmets.
