7. WARNING Care must be taken whilst using the aspida device with the man down alarm activated If the device is detached from the user s person and left on a stationary surface the man down condition will be triggered This can lead to unintentional activation of the very high volume siren As this siren sounds in excess of 100dB this may be potentially harmful to hearing To avoid nuisance alarms the device should be switched off when left unattended A NOTE The man down high volume siren causes a large strain on the aspida s batteries and as such the expected operating period for the device is significantly reduced if the man down alert is allowed to run for extended periods of time Panic Alarm In cases where a worker is in distress and still conscious it is possible to activate the ultra loud siren manually To activate the panic alarm press and hold the 6 button Document Ref PGA 801 10 December 2014 NALO iudi aspida User Manual Time weighted average TWA monitoring of carbon dioxide Carbon dioxide is toxic to the human body as concentrations increase Short term exposure to the gas can be potentially lethal Longer term exposure to more moderate levels of carbon dioxide can also be detrimental to health so health and safety bodies i e UK HSE define occupational exposure levels OEL for the gas These OELs provide a recommended safe exposure to carbon dioxide whilst under working conditions The occupationa
