[tips] hand protection series clearance book

The hand is the part that is most vulnerable to external injuries. In addition to injuries such as cuts, punctures, and fractures, there are chemical burns, electric shock burns, and paints that come into contact with wounds. On average, there are at least 30,000 finger accidents in the Pearl River Delta region each year. In fact, most hand injuries in the workplace can be prevented or reduced by wearing gloves.

The ABC below the logo corresponds to conduction cold, cold contact, and water permeability protection level.

4 Chemical protection

Anti-chemical corrosion, chemical absorption, chemical splash. EN374 indicates that the glove can guarantee a penetration time of more than 30 minutes for at least 3 chemicals (ABC represents 3 of the 12 specified chemicals respectively).

5 Impact cut protection

The standard of protection against impact performance prevents cutting of the handheld tool.

6 Power Injury Protection

Electrical insulating gloves standard, provide corresponding power injury protection.

2. Selection of hand protection products

1 Selection of Mechanical Protective Glove Coatings Mechanical resistance and chemical protection characteristics of gloves are determined by the material, formulation, production process and other factors of the glove coating. According to the requirements of the specific work station for the coating material of the gloves, the coating with the corresponding characteristics can be selected. Layer material.

Polyurethane PU

Wear-resistant, flexible, suitable for dry or slightly oily environment.

Nitrile Nitrile

Good oil resistance, water permeability and abrasion resistance.

Foam Nitrile foamed nitrile

Good oil resistance, breathability and excellent slip resistance.

Powder Nitrile Powder Nitrile

Good oil resistance, water resistance, cutting resistance and slip resistance.

Natural Latex Natural Latex

Excellent non-slip grip and good thermal insulation for oil-free environments.

PVC PVC

Good abrasion resistance, excellent non-slip grip.

2 Material selection of chemical resistant gloves The customer can choose the glove material with the corresponding characteristics according to the type, concentration, contact mode, ambient temperature, and usage habits of the chemicals in the application environment.

Natural latex

For water-based chemicals, such as alcohols, acids, alkalis have a good protective effect.

Comfortable and flexible.

Tear, pierce, wear and cut performance.

Insufficient protection against organic solvents, not oil.

A small number of people are allergic to latex proteins.

Nitrile rubber

Good artificial polymer, resistant to acids, alkalis, alcohol solvents, greases and petroleum products.

Does not contain latex proteins and plasticizers.

Better wear resistance than PVC or neoprene.

Dry environment applications have good grip, flexibility and sensitivity.

The material is slightly harder than natural latex.

Poor handling in humid or oily environment applications.

Protection against chemicals such as ketones and certain organic solvents (methylene chlorides such as trichloroethylene) cannot be provided.

PVC PVC

For many strong acidic compounds, strong bases, inorganic salts, alcohol compounds have good protection.

Stable protection performance is maintained over the temperature range from -4°C to 65°C. After special processing, the lower limit of the applicable temperature range can reach -34°C.

Easy to cut or pierce.

Aromatic compounds and ketones cannot be protected.

Neoprene rubber

Excellent protection against acids, bases, oils, and a wide range of solvents.

Stable protection performance is maintained at -17°C to 149°C.

Often used in combination with natural latex, or as a cover for natural latex, it has certain resistance to abrasion, cutting, tearing, and piercing.

Not recommended for protection of aromatic compounds.

Composite Film Silver Shield®/4H®

Known as "Worry-free" materials, it protects more than 280 chemical substances.

It is not easy to cause skin irritation when used and can be used as a glove lining.

The material is hard and not flexible enough.

Not fitting hand.

Sultry, airtight.

Poor mechanical performance.

3 Selection of glove size The choice of glove size depends on the measurement of hand circumference (A) and hand length (B). The measurement method is as shown below.

In general, Chinese adult women are suitable for No. 8 gloves, and Chinese adult men are suitable for No. 9 gloves.

3. Use and maintenance of gloves

Pre-wear inspection of chemical resistant gloves

1 Grab the cuffs and extend your thumbs into the gloves to slightly relieve the cuffs.

2 Rotate the glove two or three times inwards to inflate and inflate and magnify the glove.

3 Gently squeeze the gloves so that the glove surface is in an expanded and magnified state. Carefully inspect the glove surface for signs of discoloration, cracking, hardening, brittleness, or air leakage. Replace the gloves immediately if any of the above phenomena occurs.

Chemical protection gloves 1 Clean gloves before removing gloves. 2 Gloves can be rinsed in running water and then air dried, but the chemical resistance of the gloves may be affected. 3 When the amount of chemical substances is large, suitable solvents should be selected for cleaning. 4 Avoid using aggressive cleaning fluids. 5 After washing, dry thoroughly.

Storage of anti-chemical gloves stored in a dry, dark, room temperature environment

4. Frequently Asked Questions

How long can the anti-chemical gloves last?

The use of gloves must be based on the specific use of the environment and the use of comprehensive consideration. The type, concentration, contact method of the chemicals, user's usage habits, use time, maintenance, and the material and strength of the gloves all affect the use of the gloves.

How to choose protective gloves in jobs with oily environment operation (more oil content)?

We recommend using nitrile-coated work gloves with good oil resistance. Different types of nitrile coated work gloves can be selected depending on the amount of oil, breathability requirements, wear resistance and cut-proof requirements.

Use a utility knife to test whether the cut-proof gloves are scientific?

Not science. According to the provisions of GB/T 24541-2009, the cut-proof performance of gloves is tested by a glove cut-proof tester instead of a utility knife. How many times the test material can withstand the cutting under the standard conditions (compared with the reference material cotton) , divided into 5 levels, is used to provide protection for users when there is a risk of cuts or other mechanical cutting, and cannot be used to withstand mechanical damage caused by sharp objects in high pressure and high speed environments.

What parameters need to confirm the purchase of gloves?

1. On-site operating environment or work station (lathe, machinery manufacturing or chemical treatment, etc.); 2. Cut-proof gloves - cut-proof grade; high temperature gloves - how much temperature resistance; anti-chemical gloves - chemical type; insulating gloves - Pressure rating.
