Ear and Eye Protection

Caution: Expansion of gas from high-pressure to low-pressure produces a sound wave, the intensity of
which is a function of the gas pressure. The intensity of the sound generated by discharging the Helios Gene
Gun is ~108 decibels (db) at 400 psi; sustained noise levels of 85 db or brief noise levels of 110 db may lead
to permanent hearing damage. Hearing protection should be worn by all those in the immediate vicinity
when discharging the Helios Gene Gun. Earmuffs or ear plugs provide equivalent protection against hearing
damage. Refer to Requirements for System Operation in Section 2 for suggestions on ear protection.
Eye protection should always be worn when working with gases under high pressure.
