Wood Pellets can Emit Toxic Gasses

The Health and Safety Authority (HSA) has issued a general alert regarding the danger of Carbon Monoxide poisoning in wood pellets hoppers and storage areas.

This warning came after a fatal accident where a householder died after being overcome by an accumulation of CARBON MONOXIDE in a storage hopper for wood pellets. Carbon monoxide is a colourless, odourless and tasteless gas you won’t enen notice it killing you.  It is a highly toxic gas and easily kills.

Wood Pellet Boilers are commonly used in homes and businesses as an alternative to the oil or gas fired boilers. Wood pellets, the fuel source for these units are normally housed in a large sealed hopper/tank that is either fitted with screw feeder (auger) connected to the boiler, or the hopper/tank is mounted over the boiler for gravity feeding. Due to the enclosed nature of these hoppers/tanks the atmosphere inside can become oxygen depleted and a toxic atmosphere can accumulate. The HSA is asking all operators, maintenance personnel and users of this equipment to do the following:

1.    DO NOT ENTER or place your head into the wood pellet hopper under any circumstances. The unit can contain toxic gases.
2.    Ensure that your wood pellet hopper/tank and boiler has been installed and commissioned by a competent person. If in doubt, contact the supplier and/or manufacturer and request assistance.
3.    Ensure that the boiler is cleaned and serviced by a competent person at the frequency required by the manufacturers’ instructions.
4.    If any problems are encountered with the unit, such as, system not heating correctly, flue gas is flowing into boiler room, turn unit off and seek assistance immediately.
5.    No personnel should enter the hopper/tank unless fully trained and competent in confined space entry procedures. The hopper/tank should be fully ventilated and controls put in place to ensure safe entry as per the HSA Code of Practice “Safe Work in Confined Spaces”
6.    Ensure boiler room is well ventilated at all times to ensure no inadvertent build up of toxic gases.
7.    I would add to this BE ESPECIALLY VIGILENT WHERE YOUR CHILDREN MIGHT PLAY!!
