Cyliner Trolley
Cylinders vary considerably in size and mass (and hence stability). Purpose designed cylinder trolleys are the safest way of moving them and must be used over any but the shortest distances and over any even slightly uneven surface. You may need different trolleys for different sizes of cylinder. The wheels and tyres must be suitable for the ground or floor conditions. Always use suitable restraining chains or straps to hold the cylinder in place as firmly as possible. Make sure that your cylinder trolleys are strong enough for the job, easy to manoeuvre and adequately maintained.
Product No. 99-112
Asses the Task
Make sure the people who will be using or handling the cylinders have been trained. Understand what is in the cylinder(s), its properties, hazards and emergency actions. Examine the cylinders and decide whether you can manage alone or need assistance.
Plan & Check the Result

Check whether it is accessible with a trolley and if there are any obstacles or slippery areas or whether any are likely to appear (due to leaves, frost, temporarily stored materials etc). Check whether the route is well lit throughout and whether there are any site roadways to cross. If there are any inclines establish whether you need powered mechanical assistance. In particular, think what would happen if you lost control of the trolley on a slope and what risk this would pose to other people. Be frank and assess your strength and fitness and whether you will need to rest. Make sure you will not exceed the Manual Handling Regulations. If you have to move the cylinder via a stairway, close it to pedestrians and get assistance. If you use a passenger lift or goods lift, close it to all passengers. Never travel in a lift with the gas (unless the cylinder(s) contain breathable air). Instead, get an assistant to meet the lift at its destination.

NOTE:
All free-standing cylinders are liable to topple over. Large cylinders require special care because of their greater mass and size.

Upright cylinders must be secure. If they are not physically restrained, they must be under the user's direct control. NEVER turn your back on a free-standing cylinder. And if a cylinder falls over - NEVER attempt to stop or catch it; GET OUT OF THE WAY!

Never roll cylinders along the floor on their sides because the valve could be damaged and the cylinder will be out of control.

Do not attempt to move cylinders with regulators attached and/or when connected to a system i.e. when the cylinder valve is open.

Large gas cylinders can be moved by churning but do not churn cylinders fitted with hand-wheel operated valves. Only churn over short distances on firm and even surfaces.

Don't churn too quickly
Don't tilt the cylinder too far over
Never try to churn two cylinders at once

Gas Safety Issues - Cylinder Storage
  • Drain and duct openings
  • Adequate ventilation
  • Signs and notices (hazard warnings and prohibitions)
  • Space, lighting (safety of electrical fittings around flammable gases) and cleanliness
  • Facilities to prevent cylinders from falling (chains or straps)
  • Well made, well drained and even concrete floor surfaces
  • Extremes of temperature
  • Weather protection (including direct sunlight)
  • Authorisation of access
  • Contents inventory
  • Emergency actions: fire fighting, evacuation etc. (inform the emergency services which gases and in what quantities you are keeping)
  • Emergency equipment (extinguishers, breathing apparatus etc.)
 
 
Keeping Cylinders in the Laboratory
  • Only keep the absolute minimum in the laboratory. Separate the cylinders from populated workspaces
  • As far as possible, segregate oxidants from fuels (eg nitrous oxide from dissolved acetylene where atomic absorption spectrophotometry is being carried out)
  • DO NOT keep very toxic or pyrophoric gases indoors
  • Partitions should be fire resistant and suitable forced ventilation (10 air changes/hour) may be necessary
  • Gas detection and alarms (oxygen deficiency, oxygen enrichment, explosimetry, toxic gas warning etc) should be seriously assessed
  • Your 'Risk Assessments' will establish what (if any) emergency equipment will be needed.
