Bunfight-specific risks
Overcrowding Reduced space in walkways and entrances. Risk of Students panicking because of tight spaces / confinement. Crushing against fixed structures from pushing and shoving. Representatives will not block walkways when engaging with attendees L H M
Display or equipment falling over All displays and equipment are to be properly stacked and secured, preventing risk of collapse and resultant injury to persons nearby. Tables must be strong enough to carry weight of displayed equipment. Excessively heavy items such as lead-acid batteries to be placed on floor. L L L
General Risks
Slips, trips and falls Minor injuries, bruising, sprains. People in proximity. 4 2 8 All cables routed away from walkways. Loose cables to be appropriately secured to prevent trip hazards. 2 2 4
Operation of electrical equipment Electric shock/electrocution Equipment users. 3 5 15 Equipment should not be used in damp/wet conditions. Equipment shall not be operated while circuitry is exposed unless absolutely necessary. Equipment shall not be operated using damaged wires. 1 5 5
RF energy Warming of body tissue People in close proximity of transmitting antenna 3 3 9 Power limited to 100W. All feeders placed well out of reach. Good RF earth for equipment. 2 3 6 Warning notice to be positioned around antennas warning to keep distance.
Manual handling Musculoskeletal injuries, cuts, bruises and crushing. People involved in manual handling activities. 4 3 12 Members must ensure that they follow proper lifting procedure, reminding others when necessary. Ensure that the appropriate number of people are used to carry the load, depending on weight of load and capacity of those involved in the lift. 2 3 6
Lead-acid batteries Shorting of contacts could lead to damage to the cells or fire. Equipment, storage location. 2 5 10 Contacts are taped over for storage and transportation. 1 5 5
Wires/ropes at neck/head height Walking/running into partially assembled/erected antennas could cause head/neck injury or tangling. People in proximity to wires/rope. 3 3 9 Ensure everyone present are aware of the construction going on. 2 3 6 Warning signs, markers to be placed on antenna where possible.
Lightning strike on antenna or mast If someone is operating a radio when the antenna is struck by lightning then there is risk of electric shocks or burns to the operator. Equipment users, People in close proximity to mast or antenna. 2 5 10 Ensure that radios are not operated during stormy weather. Install lightning arrestors on the feeds to permanent equipment installations. Temporary masts shall not be used during stormy weather and shall be take down as a precaution upon awareness of potential storms if safe to do so. 1 5 5

Tripod Mast
Mast falling over If the mast is not secured properly then it may fall over, causing injury to people who happen to be underneath or beside it at the time. People in proximity to mast. 3 3 9 Ensure that the mast is properly secured ("guyed") during operation and that there is someone supporting it while the guys are being installed. Mast should not be errected during storms/highwinds. 2 3 6
Guy ropes Tripping or falling over guy ropes People in proximity to mast. 4 2 8 Ensure that the guy ropes do not cross footpaths or walkways. In situations where the guys are hard to see (e.g. at night), affix flags or markers to each to aid visibility. 2 2 4
