Guiding Principles for Safe and Secure Inflatable Anchoring
When setting up an inflatable, it's critical to make sure every anchor point is used properly to comply with EN14960 regulations. Every anchor must provide 167kn of resistance in winds reaching 24mph. There are several ways to achieve this, depending on the type of ground you are working with.
Ground anchoring options include pegging, sandbagging, water bails, Thunderbolts, raw bolts, or tethering to a fixed object that can resist 167kn of force. If you're working on soft ground like grass, you can use 16mm rebar pegs that are 380mm in length and 100mm return. On hard standing surfaces, you can tether the inflatable to objects with a weight or resistance greater than 167kn, such as fence posts, cars, lampposts, or skips. Alternatively, you can use rawbolts or Thunderbolts with a heavy duty drill, bolts, and suitable ratchet to install them.
When using ropes, chains, or locks, they must be thick enough to withstand 163kg, and they should be kept out of reach of users. It's also important to make sure bolts are rated over 163kg to ensure they're suitable for use with inflatables. Avoid using bolts on block paving or flags, as they usually have a low resistance due to the bed of sand they are laid on.
When working on hard standing surfaces, it's recommended to take photos of the area beforehand to assess if it can withstand the pressure of bolts or rawbolts. Be cautious of tarmac that is in poor condition, as it may not be able to withstand the force. If you're unsure about the suitability of a surface, it's best to decline the job.
In wet or boggy ground, use double pegs or walk away from the job if necessary. Safety should always be the top priority. The same goes for rawbolts or tethering - if you can't achieve 167kn or 163kg, it's best to walk away from the job.
In conclusion, the most critical factor in anchoring an inflatable is achieving the minimum 163kg of resistance on every anchor. This requirement is non-negotiable and the liability falls solely on you to make sure you comply with EN14960 regulations. When in doubt, always prioritize safety and choose the anchoring method that will provide the most secure hold for your inflatable setup.
Final wise words for clients
"It is important to monitor the wind and rain conditions before and during your hire. To stay informed, we recommend checking the Government's Met Office website or downloading the app at regular intervals. If the wind speed is predicted to reach cautionary levels of 19-24 MPH, it is crucial to check the forecast every 15 minutes to ensure the safety of all users. The Met Office website provides updated information at https://www.metoffice.gov.uk/ or you can keep an eye on the Beaufort scale for practical observation."
