Safety and usage instructions for Granberg 114.0660W nitrile chemical resistant gloves, including performance levels, chemical permeation data, and maintenance guidelines.
Table of contents
Product Overview
The Granberg 114.0660W is a Category III Personal Protective Equipment (PPE) designed to protect hands against various chemicals and mechanical wear. These nitrile gloves feature a polyester lining and a long, welded nitrile cuff for extended protection. They are suitable for short-term contact with all types of food.
Safety and Limitations
Important: These gloves protect against bacteria and fungi but do not protect against viruses. They are not intended for use where there is a risk of entanglement with moving machine parts. While they meet puncture resistance requirements, they may not be suitable for protection against sharply pointed objects like hypodermic needles. If you have a latex allergy, please note that while these are nitrile, you should monitor for any signs of sensitivity.
The protection levels provided are based on laboratory tests performed on the palm area. Actual workplace conditions, such as temperature, abrasion, and degradation, may significantly reduce the effective protection time compared to laboratory results.
Usage and Sizing
Select the correct size for your hand to ensure dexterity and reduce fatigue. To put on the gloves, hold the cuff, align your thumb with the glove's thumb, and slide your hand in. Adjust the fingers for a proper fit. To remove, pull by the fingertips if the gloves are clean. If contaminated, hold the cuff and pull toward the fingers to invert the glove.
Maintenance and Storage
Inspect gloves for damage before every use. If in doubt, discard and use a new pair. Gloves can be cleaned with a damp cloth, but this does not stop chemical permeation processes. Store unused gloves in their original packaging in a dry environment between 5-25°C, away from direct sunlight. When stored correctly, mechanical properties remain stable for up to three years from the date of manufacture.
Technical Compliance
These gloves comply with EN 388:2016+A1:2018, EN ISO 374-1:2016+A1:2018 (Type B), EN ISO 374-5:2016, and EN ISO 21420:2020. For detailed chemical permeation data (n-Heptane, Sodium hydroxide, Hydrogen peroxide, Formaldehyde), refer to the technical tables provided in the product documentation.

Practical help
Common problems
Gloves feel uncomfortable or cause fatigue.
Ensure you are using the correct size. Poorly fitting gloves reduce dexterity and increase hand fatigue.
Signs of tearing, swelling, or degradation.
Discontinue use immediately as the protective barrier may be compromised.
Chemicals entering the glove.
Ensure chemicals or residuals cannot enter via the cuff and come into contact with the skin.
Before use
- Inspect the gloves for any physical damage or holes.
- Verify the glove size matches your hand for proper dexterity.
- Check if the chemical you are handling is listed in the permeation test table.
- Ensure the cuff is properly positioned to prevent chemical ingress.
Specs in practice
- EN 388:2016+A1:2018
- Standard for protection against mechanical risks (abrasion, cut, tear, puncture).
- EN ISO 374-1:2016 Type B
- Indicates the glove provides a breakthrough time of at least 30 minutes for at least 3 chemicals from the defined list.
- Breakthrough Time
- The time it takes for a chemical to permeate through the glove material at a rate of 1 microgram per square centimetre per minute.
Model compatibility
- Suitable for short-term contact with all types of food.
- Not for use with viruses.
- Not for use near moving machinery parts.
