When conducting workplace air sampling, reliability is key. Operators need to know that the equipment they rely on to collect and sample the air for respirable dust and other hazards will yield consistent and accurate data.
Casella, an expert in hazard sampling and environmental monitoring, has worked with the Health and Safety Executive (HSE) to undertake intensive testing of its Cyclone Air Sampling heads to ensure that the heads meet the ACGIH/ISO/CEN (EN 481) standard, the collection efficiency curve against which respirable fractions are measured. The intensive testing has confirmed that Casella’s Cyclone sampling heads meet this standard when sampling at the published flow rate of 2.2 litres per minute.
Flow rate is a crucial factor for correct air sampling results. The Cyclone is manufactured to sample respirable dust at a specific air-flow rate. If it is not sampling correctly at the specified flow rate the concentration of dust can be over or under estimated; a concerning outcome when poor data could have a direct and negative impact on workplace safety and worker health.
“Peace of mind is the watchword when it comes to air sampling; having the confidence that the sample taken is accurate,” explains Tim Turney, Casella Global Marketing Manager. “When sampling heads meet international standards and operate according to manufacturer specifications in regards to sampling performance, there is peace of mind that respirable hazards are being correctly monitored for.”
“The confirmation from the HSE that our Cyclone heads operate as intended is welcome news. Recent testing of cyclones by other manufacturers has shown they were not meeting the EN481 standard, calling into question all past air samples taken with those heads, resulting in end users having to change equipment going forward. Our original performance to the standard at a 2.2 litres/min flow rate still stands, giving end users confidence in the results.”
