• DNELs
DNELs for OSH purposesIn Germany, occupational exposure limits (AGW) of the Technical Rules on
Hazardous Substances (TRGS) 900 continue to constitute workplace atmospheric limit values that
are binding upon employers. Should no AGW and for example no maximum workplace concentrati
on (MAK value) of the German Research Foundation (DFG) be available, the employer must also
consider the DNEL during risk assessment.(Source: Institut für Arbeitsschutz der Deutschen Gesetz
lichen Unfallversicherung (IFA))current values are available: http://www.dguv.de/ifa/gestis/gestis-dnelliste/

• Additional OccupationalExposure Limit Values forpossible hazards duringprocessing: Compliance with the general dust limit value(s) (lung penetratingand/or inhalable fraction) must be ensured.• Additional information: The lists valid during the making were used as basis.• Recommended analysisprocedures: cobalt:- NIOSH, no. 7027- OSHA, no. ID 121 / ID-125• Personal protective equipment:• General protective andhygienic measures: Keep away from foodstuffs, beverages and feed.Wash hands before breaks and at the end of work.• Respiratory protection: In the case of dust formation (limit value exceeded),breathing apparatus must be worn.Time limits for wearing must be observed.Breathing mask, apparatus with particle filter P2 or P3,for example:- Full face mask (EN 136)- Breathing mask (EN 149) FFP2 or FFP310 times the limit value (FFP2)30 times the limit value (FFP3)Recommendation: P3• Protection of hands: Avoid repeated and prolonged contact with the skin, useprotective gloves.Preventive skin protection by use of skin-protectingagents is recommended.• Material of gloves: Material of gloves should be impenetrable (e.g. nitrile caoutchouc). Depending on use heat protective gloves are required.• Penetration time of glove material -• Eye protection:Tightly sealed goggles (EN 166)• Limitation and supervision ofexposure into the environment The legal issue values and limitations are to be paid attention!
