Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Ensure adequate ventilation, especially in confined areas. Ensure that eyewash stations and safety showers are close to the workstation location.

Hands

Glove material Neoprene Nitrilerubber Breakthrough time Glove thickness EU standard Glove comments > 480 minutes 0.45 mm Level 6 EN 374 As tested under EN374-3 Determination of Resistance to Permeation by Chemicals >480minutes > 0.2 mm. Inspect gloves before use. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information) Ensure gloves are suitable for the task: Chemical compatability, Dexterity, Operational conditions, User susceptibility, e.g. sensitisation effects, also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion. Remove gloves with care avoiding skin contamination.

Eyes

Wear safety glasses with side shields (or goggles) (European standard - EN 166)

Respiratory

When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. Use a NIOSH/MSHA or European Standard EN 136 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced Recommended Filter type: Particle filter Maintain adequate ventilation

Skin/Body

Long sleeved clothing.

Environmental

Prevent product from entering drains.
