Can I use steel mesh gloves in activities involving electric saws?

Steel mesh gloves are not designed or tested to provide protection against electric saws, saw teeth, or other rotating equipment.

The ISO 13999-1 standard itself specifies the functions for which steel mesh gloves are applied: "activities in which manual knives are used, such as in the processing of meat and similar products in refrigeration establishments."

As stated in the "d" clause of the Instructions for Use: "protection is limited to cuts and strikes from manual knives." ISO 13999-1

SCOPE/OBJECTIVE: This International Standard specifies basic requirements and laboratory tests for gloves and sleeves constructed from steel mesh and rigid arm protectors used for body protection in activities in which manual knives are used, such as in the processing of meat and similar products in refrigeration establishments.

REQUIREMENTS: gloves must meet the following requirements of the standard: size requirements; construction requirements; resistance to tensile and knife penetration; marking requirements and information provided by the manufacturer.

What is the difference between expiration date and shelf life?

The product's expiration date is determined by the time that the equipment maintains its quality and protection characteristics against the risks for which the PPE* is indicated.

In the case of equipment, as they are not perishable products, the expiration dates are usually long or undetermined.

The useful life depends on several factors that involve the type of activity such as time and frequency of use, manipulated material, task performed, user care, compliance with usage and maintenance instructions, among others. In other words, it is a variable time, never exceeding the product's expiration date.

Given these variables, the definition of useful life will only be possible after practical tests are performed at the workplace.

The duration or useful life will always be an average of the results obtained in the tests, never exceeding the product's expiration date.

We emphasize that the equipment must be immediately replaced when damaged, as provided for in NR-6* item 6.6.1 subparagraph e.

Note: the maximum resistance and use limits, established in the tests and informed in the technical sheets of each model, must be respected.

Technical Note No. 176 of 07/18/16/CGNOR/DSST/SIT* (Expiration Date vs Useful Life of PPE) also provides clarifications about the difference between expiration date and useful life.

How to dispose of safety gloves?

After use, Personal Protective Equipment (PPE) can pose a health and environmental risk as they may be contaminated with hazardous waste. Therefore, we need to properly dispose of each type of product, taking into account the type of contaminant present in the equipment. To do so, we must follow current laws and regulations.


Regulations may vary depending on your state and/or municipality.

The PPE must be rendered unusable before being discarded.

All companies generating solid waste must implement the Solid Waste Management Plan (PGRS), which guides users with information on the disposal of chemical or solid waste from industrial processes that need to be discarded after use.

This plan should be based on Federal Law No. 12,305 of August 2, 2010.

Article 1. This Law establishes the National Solid Waste Policy, providing for its principles, objectives and instruments, as well as for the guidelines relating to the integrated management and management of solid waste, including hazardous waste, the responsibilities of generators and the government and the applicable economic instruments.

In addition to this, the following laws also apply:

11,445, of January 5, 2007. 9,974, of June 6, 2000. 9,966, of April 28, 2000.

We must also pay attention to the rules established by the agencies of the National Environmental System (Sisnama), the National Health Surveillance System (SNVS), the Unified System for Agricultural and Livestock Sanitation (Suasa), and the National Metrology, Standardization and Industrial Quality System (Sinmetro).

Using the example of the state of São Paulo, to determine the type of disposal for the PPE, in the Certificate of Movement of Environmental Interest Waste (CADRI), the equipment must be included in the Characterization Report (NBR 10.004/2004 - Solid waste - Classification) issued by a laboratory authorized to determine if the product is contaminated or not, and in which class it will be included:

Class I Waste - Considered hazardous, due to contamination during use. Disposal: Incineration or Co-processing. Class II Waste - Considered non-hazardous, meaning without aggressive chemicals. Disposal: Industrial landfill.

Can I use steel mesh gloves for activities involving electric saws?

In the pictogram for protection against mechanical hazards, the tests are represented by up to 6 alphanumeric characters, with values ranging from 1 (one) to 4 (four) for abrasion, tearing, and puncture, and 1 (one) to 5 (five) for cut resistance, with 1 (one) being the worst result.

From left to right, the 1st character represents abrasion resistance, the 2nd character represents cut resistance (coupe method), the 3rd character represents tear resistance, the 4th character represents puncture resistance, the 5th character represents cut resistance TDM (additional test provided in EN ISO 13997 standard, with values ranging from A to F, with F being the best result), the 6th character (P) represents additional protection against impact.

Note: "X" indicates that the product has not been tested or the test is not applicable. "0" indicates that the product is below the minimum performance level for the risk. The absence of the 6th character (P) indicates that the PPE is not approved for impact protection.

Which PPEs must obtain a conformity certification issued by INMETRO?

Considering the Technical Cooperation Agreement signed between Inmetro and the Ministry of Labor, which delegates powers to Inmetro to develop Quality Technical Regulations and Conformity Assessment for Personal Protective Equipment and to directly or indirectly supervise, throughout the national territory, through delegated agencies, the following equipment must obtain conformity certification issued by INMETRO: safety belt, fall arrest device, and safety lanyard; safety helmets for use in industry; surgical gloves and non-surgical natural rubber gloves for healthcare; insulating rubber gloves; filtering half mask for particles - PFF (Filtering Facepiece) 1, 2 and 3.

Note: Chemical protection gloves (natural rubber, synthetic rubber, natural and synthetic rubber mixtures, and polyvinyl chloride), are not subject to health surveillance regulations and are exempt from compulsory certification by INMETRO.

Can I perform washing and/or sanitization of my PPE?

Yes. The cleaning and/or sanitizing procedure of Personal Protective Equipment (PPE) can be carried out, and is established in the new version of Regulatory Standard NR-06 - Personal Protective Equipment - PPE.

Item 6.5.1 It is up to the organization, regarding the PPE:

a) to be responsible for the periodic cleaning and maintenance, when applicable, in accordance with the information provided by the manufacturer or importer;

Item 6.8.1 The national manufacturer or importer shall:

b) market the PPE with instructions manual in Portuguese language, guiding its use, maintenance, cleaning and sanitizing processes, restriction and other references to its use;

Item The information on the cleaning and sanitizing processes of the PPE should indicate, when applicable, the number of sanitizations above which it is not possible to guarantee the maintenance of the original protection, requiring the replacement of the equipment.

Washing and/or sanitizing PPE helps to preserve the equipment's service life, avoiding premature disposal due to dirt and providing savings in safety resources and waste disposal. It reduces the environmental impact by avoiding waste and collaborating in the protection and conservation of the environment.

The benefits are many! And it also guarantees healthier hands and well-being for the worker.

But remember: analyze what can be washed and/or sanitized, as some PPEs are disposable.

DANNY recommends washing and/or sanitizing PPEs 1, in order to rationalize consumption, optimize safety investment, reduce waste and material waste, and thus contribute to the reduction of pollution and environmental damage. After all, we are part of this ecosystem! We need to reverse negative impacts and encourage positive ones.

Often we discard equipment that can still be used. Acting with environmental responsibility is ensuring the continuity of current and future generations. How about starting to change our daily attitudes and have a more responsible consumption? So, be aware. Protecting the environment is our responsibility so that future generations can enjoy all the resources that our planet offers.


  • Sanitizing: removal of contaminants that require specific care or procedures. It includes decontamination and disinfection processes.
  • Cleaning: removal of dirt and residue manually or mechanically, using common use products, such as water, detergent, soap or sanitizer.

For more information, consult the product technical data sheet and instruction manual.

What are the types of cuff finishing for safety gloves?

Safety gloves without textile support

Folded cuff, scalloped cuff or straight cuff

Does not allow residues to become embedded in the glove cuff, and offers greater ventilation. *Fold cuffs when working with liquids to prevent them from running onto the arms and inside the gloves.

Safety gloves with textile support

Knitted cuff

The knitted cuff fits perfectly on the user's wrist and prevents solid particles from entering inside the glove. Nylon and elastane help maintain the shape of the cuff, and even after washing and/or sanitizing, offer an excellent fit.

Velcro closure cuff

Allows the user to control the fit, providing better dexterity and greater comfort. Prevents solid particles from entering inside the glove.

Safety cuff

Canvas cuff provides greater ventilation. Offers better protection over the wrist area. Allows for quick donning and doffing of the glove, which is why it is also known as a quick-release cuff.


How are impact gloves tested and classified according to ANSI 138 standard?

The test is conducted by dropping a drop striker (a falling mass) onto the impact points of the glove, registering the force transferred in kilonewtons (kN). This test is repeated eight times for the knuckles and ten times for the fingers. Gloves are classified based on all test results and the average.

To be classified as ANSI/ISEA 138 level 1, 2, or 3, the average and all test results must be within the classification parameters below.

                                                         Classifications for impact resistance:

LevelSpecified value (kN) AverageSpecified value (kN) All.
1≤ 9,0≤ 11,3

Note: the correlation or equivalence between the performance levels of the standards is related only to the metacarpal region, since according to item 4.4.2 of EN 388 standard, due to the test method (dimensions of the test sample), protection against impacts on the fingers cannot be tested. Tests for both standards are performed with a mass of 2.5 kg, which produces an impact energy of 5 J.

How are cut-resistant gloves classified according to ANSI 105 standard?

To be classified for protecting the user's hands against cutting agents, ANSI 105 requires gloves to undergo ASTM F2992-15 standard using the TDM testing machine, a test that measures the force (in grams) required for the blade to cut through the glove sample over a 20mm cutting stroke.

The current version of ANSI/ISEA 105-2016 (ASTM F2992-15 method) classifies cut resistance levels from A1 to A9.

Gloves with a cut level of A1, which is the lowest rating, must resist a cutting force of at least 200 grams and can withstand up to 499 grams before the blade pierces the sample. In the case of level A9, which is the highest rating, gloves must resist a cutting force of at least 6000 grams before the blade pierces the sample.

Can an ergonomic belt be used to correct a spine injury?

No, it is recommended to consult a doctor if the user has already experienced any spinal injury. The ergonomic belt is recommended for users who have not yet shown any signs of back pain and are extremely useful in preventing back pain and injuries in various work functions.

The proper use of the ergonomic belt allows for correction of the movement of dorsal/lumbar flexion to help maintain good posture and prevent spinal injuries when lifting weights.

It is recommended for activities that involve lifting heavy objects, loading and unloading materials, and other activities even if they do not involve handling loads (for example, drivers, security personnel, quality control, maintenance, and others) and any other activity that involves the spine.

Note: the ergonomic belt helps to maintain good posture. Training on how to handle loads, maintain posture, occupational gymnastics, and a rotation program in work areas where repetitive movements occur are essential to prevent injuries and fatigue among employees.

Why do some models of safety glasses appear to have a prescription?

What gives the feeling that safety glasses have a prescription is the curvature of the lens. People with greater sensitivity (which may vary from person to person) may experience headaches during use. In this case, it is valid to look for a model with less lateral curvature.

Attention! There are glasses that are not made with optical polycarbonate (virgin) and can cause health damage.

All Danny safety glasses are made of high-quality and highly resistant optical polycarbonate.

Another important detail to observe is the brightness in the work environment, as prescribed in Regulatory Standard NR-17 (Ergonomics), which establishes minimum levels of illumination.

17.5.3 There must be adequate lighting, natural or artificial, general or supplementary, appropriate to the nature of the activity in all workplaces. General lighting must be evenly distributed and diffuse. General or supplementary lighting must be designed and installed to avoid glare, annoying reflections, shadows, and excessive contrasts. The measurement methods and minimum lighting levels to be observed in workplaces are established in Occupational Hygiene Standard No. 11 (NHO 11) of Fundacentro - Evaluation of Illumination Levels in Internal Work Environments.

Remember! Dirty, stained, scratched, with tonal differences or any alterations lenses can also cause distortion, difficulty in vision, and headaches.

Choosing the appropriate lens for each environment provides greater visual comfort.

Yellow Lens | Indoor or outdoor environments with low brightness.

Gray Lens | Indoor or outdoor environments with high brightness.

Clear Lens | Closed environments with artificial lighting or outdoor environments.

In-Out Lens | Indoor or outdoor environments with light variation.

Green Lens | Indoor or outdoor environments with high brightness.

Ultraviolet protection does not depend on the lens color, as it is in the polycarbonate itself, that is, even the clear lens filters more than 99.9% of UVA and UVB radiation.

Do Danny safety glasses have protection against ultraviolet rays UV-A, UV-B, and UC-C?

All Danny safety glasses have protection against ultraviolet radiation (UV-A, UV-B, and UV-C).

The American National Standard for Occupational and Educational Personal Eye and Face Protection Devices ANSI/ISEA Z87.1-2015 establishes requirements for protection against ultraviolet radiation for all lens shades.

Ultraviolet radiation (UV) is electromagnetic energy with wavelengths from 200 to 380 nm*, being:

UV-A: near ultraviolet with wavelengths from 315 to 380 nm.

UV-B: effective ultraviolet with wavelengths from 280 to 315 nm.

UV-C: far ultraviolet with wavelengths from 200 to 280 nm.

In the Approval Certificate - CA, through the "approved for" field, it is possible to identify if safety glasses are approved for ultraviolet radiation.

Safety glasses approved in this regard must display the "U" marking, which presents a scale from 2 to 6.

Note that it is not possible to find the individual result of the far ultraviolet radiation test (UV-C), this is because the effective UV transmittance test requirement (UV-B) already contemplates the wavelength of UV-C radiation.

  • Nanometer (nm): a unit of length wavelength equal to one billionth of a meter (10 -9 meters).

Note: ANSI Z87.1-2003 standard does not establish requirements for transmittance against ultraviolet radiation for clear (transparent) lenses.

How to read the performance classification of a safety glove approved for thermal risks (heat and fire)?

On the pictogram for heat and/or fire protection, the tests are represented by 6 alphanumeric characters, with values ranging from 1 (one) to 4 (four), with 4 (four) being the best result. From left to right, the 1st character represents flame resistance, the 2nd character represents resistance to contact heat, the 3rd character represents resistance to convective heat, the 4th character represents resistance to radiant heat, the 5th character represents resistance to small splashes of molten metal, and the 6th character represents resistance to large splashes of molten metal.

Note: "X" indicates that the product has not been tested or the test is not applicable. "0" indicates that the product is below the minimum performance level for the risk.

How to read the performance classification of a safety glove approved for thermal (cold) hazards?

In the cold protection pictogram, the tests are represented by 3 alphanumeric characters. From left to right, the 1st character represents resistance to cold by convection (thermal insulation), with values ranging from 1 (one) to 4 (four), with 4 (four) being the best result. The 2nd character represents resistance to cold by contact (thermal resistance), with values ranging from 1 (one) to 4 (four), with 4 (four) being the best result. And the 3rd character represents resistance to water penetration, with values ranging from 0 (zero) to 1 (one), where "0" indicates penetration and "1" indicates no penetration.

Minimum requirements: the glove must obtain at least level 1 performance for resistance* to abrasion and tearing resistance.

  • Level according to EN 388 standard - Safety gloves against mechanical risks.

Note: "X" indicates that the product was not tested or the test is not applicable. "0" indicates that the product is below the minimum performance level for the risk.

Can I use personal protective equipment (PPE) with an expired approval certificate (CA)?

Yes, as long as the PPE was purchased within the validity period of the CA.

Therefore, the employer must pay attention to the fact that, when purchasing PPE, the CA must be valid. Once the PPE with a valid CA is acquired, it is necessary to observe the product's expiration date and the instructions for use and conservation provided by the manufacturer/importer.

In technical note DSST/SIT* no. 146/2015, it is understood that PPE can only be commercialized with a valid CA, but it is now allowed to use PPE until its expiration date, as long as it was acquired with a valid CA.

Note: Distributors and resellers must be aware that the change is only valid for the end customer.
