ALS offer nationwide, full COSHH testing / fume cupboard testing services to ensure your equipment meets your legal duties under the regulations, and your equipment kept safe.
To comply with the legal requirement, typically, your fume cupboard testing or LEV testing should be on an annual basis, testing your equipment against the baseline performance standard.
Contact us to schedule a COSHH testing visit; particularly around the school holidays, it's wise to get this booked in early.
