Monitoring methods
BS EN 14042:2003 Title Identifier: Workplace atmospheres. Guide for the application and use of procedures for the assessment of
exposure to chemical and biological agents. MDHS14/3 General methods for sampling and gravimetric analysis of respirable and
inhalable dust

Exposure Controls

Engineering Measures
Ensure that eyewash stations and safety showers are close to the workstation location. Wherever possible, engineering control
measures such as the isolation or enclosure of the process, the introduction of process or equipment changes to minimise release
or contact, and the use of properly designed ventilation systems, should be adopted to control hazardous materials at source.

Personal protective equipment

   Eye Protection                Goggles (European standard - EN 166)

   Hand Protection                  Protective gloves

    Glove material     Breakthrough time  Glove thickness   EU standard             Glove comments
      Natural rubber     See manufacturers               -          EN 374             (minimum requirement)
        Nitrile rubber       recommendations
       Neoprene
       PVC
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.

   Skin and body protection       Long sleeved clothing

   Respiratory Protection       When workers are facing concentrations above the exposure limit they must use
                                      appropriate certified respirators.
                              To protect the wearer, respiratory protective equipment must be the correct fit and be used
                               and maintained properly

   Large scale/emergency use    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: Particulates filter conforming to EN 143

   Small scale/Laboratory use     Use a NIOSH/MSHA or European Standard EN 149:2001 approved respirator if exposure
                                              limits are exceeded or if irritation or other symptoms are experienced.
                           Recommended half mask:- Particle filtering: EN149:2001
                           When RPE is used a face piece Fit Test should be conducted


Hygiene Measures                Handle in accordance with good industrial hygiene and safety practice.
