||HAZARD / TOPIC||
BRIEF DESCRIPTION / ACTION REQUIRED
|March||Explosion involving liquid nitrogen||Liquid nitrogen||Risk assessments for work involving storage of material in liquid nitrogen must be reviewed to: consider the risk of vials exploding; identify control measures (precautions) to reduce the risk of injury should the vial explode; communicate the control measures (precautions) to everyone involved in the work|
|March||Fire in domestic appliance||Fire||A small fire occurred in a tumble dryer at a student residence earlier this month, caused by a build-up of fluff in the filter. Simple, quick cleaning and maintenance could have prevented this fire, which if it had spread could have been a lot worse.|
|April||Water Systems||Legionella||Departments who operate any water systems not managed by UCL Estates must appoint an ‘Appointed Person (Legionella); maintain a list of water systems, specific items of equipment or types of equipment that could present a risk of exposure to legionella bacteria; assess and control the risk of exposure|
|May||Ebola Virus||Ebola Virus||There is an outbreak in the Democratic Republic of the Congo. If you are travelling to this region your risk assessment will need to be reviewed. You should always refer to the Foreign and Commonwealth Office for advice before travelling abroad.|
|June||Reporting Accidents||RIDDOR Compliance||RIDDOR requires UCL to report all serious workplace incidents and accidents to the HSE within 10 days of the incident occurring. If your department relies on specific persons to report accidents on riskNET then by 31 July 2018 you must ensure that you have arrangements in place to cover for planned and unplanned absence of these staff.|
||Fire||If you have a Liebherr -20°C freezer model GG5210 that is two years old or more your department should carry out an inspection of the freezer.|
Once a lithium ion battery catches fire, it can be very difficult to extinguish, with the fire sometimes lasting for weeks! If you are using or storing lithium ion batteries you should:
Bunsen Burner Wire Gauzes
Two suppliers of scientific equipment have supplied mesh gauzes with asbestos-containing centres. If you are unsure about gauze coatings assume that it contains asbestos.
You should not handle, use or move wire/mesh gauzes until you have checked with the supplier to find out whether they are likely to contain asbestos. If asbestos content is confirmed or cannot be ruled out, the gauzes must be taken out of use and disposed of in accordance with relevant published guidance.
||Fire in a dust extraction unit||
Earlier this year a fire broke out in a workshop dust extraction unit. A spark ignited dust and debris which had been allowed to build up for some time. To prevent fires and ensure effective operation of dust extraction units Departments must:
Ensure the risk assessment for dust extraction units states the frequency of:
Keep written records of all dust extraction unit checks and maintenance to show that it has been done and who was responsible for doing it.
An acid waste container exploded inside a fume cupboard, shortly after being placed inside. A member of staff was splashed around their stomach area, causing minor chemical burns. The laboratory was found to have no spill kit, eye wash station or emergency procedures.
What was the cause?
Incompatible waste was mixed together in the container. Up to 20 litres of waste had accumulated in the laboratory, although on average less than 1 litre is produced per month.
What lessons can be learned?
Picric Acid Danger
Picric acid (2,4,6-trinitrophenol) can be highly explosive if not stored properly - crystals can form on the cap and bottle which make the chemical hazardous. If crystals have formed you must secure the store to prevent access.
To ensure safe storage you must:
