Noise applies to gas SJPs only. The produced noise level may often exceed 85dBA.

Silencers can be installed on the LP inlet and the discharge line of the SJP to prevent noise travelling through the interconnecting pipe work. In cases where noise emitted directly through the body of the SJP exceeds the acceptable limit, the entire SJP can be lagged with acoustic insulation materials. The normal acceptable limit is generally 85dBA at 1.0m from the SJP. There are, however, exceptional cases where lower noise level is required.
