Safety Regulations
1.2.2 Additional safety regulations for cooled incubators with CO
2
supply.
Warning!
Danger of suffocation. CO
2
can have a suffocating effect in high
concentrations. In normal operation, the cooled incubator gives
off small amounts of CO
2
to its surroundings. You should therefore
ensure that the room in which it is installed is properly ventilated.
Always close the stop valve or pressure reducer on the gas bottle if
there is no gas bottle connected or if the bottle connected is empty.
Warning!
High concentrations of CO
2
can cause cold burns or frostbite.
Avoid contact with CO
2
gas to the eyes and skin.
Warning!
Gas bottles may burst or explode at high temperature. Keep the gas
bottles away from open flames. Do not store gas bottles at or above
50 °C and ensure that the location is always well-ventilated. Prevent
water from penetrating as well as backflow into the gas bottles. It is
essential that you read the safety notes and regulations of the gas
suppliers.
CO
2
is not a dangerous substance in terms of the German Hazardous Substances Ordinance
(GefStoffV). You should nevertheless familiarise yourself with the applicable safety regulations
prior to handling such gas bottles.
1.3 Safety labels
Warning signs for dangerous UV radiation in the working
area are attached to the doors or cooled incubators
with interior UV lighting ( Fig. 1 ). They indicate that
either the lighting has to be switched off or UVsafety
goggles are required when the door is opened.
These stickers must not be removed and must always
be well visible. If they become unrecognisable or if they
peel off, they must be replaced. They can be ordered
from Memmert customer service.
1.4 Requirements of the operating
personnel
The cooled incubator may only be operated and maintained by persons who are of legal age,
and who have received relevant instructions. Personnel who are to be trained, instructed or
who are undergoing general training may only work with the appliance under the continuous
supervision of an experienced person.
The cooled incubator may only be transported (with a forklift truck or manual pallet jack)
by persons, who are trained for this work and are familiar with the corresponding safety
regulations.
Repairs may only be performed by qualified electricians. The regulations in the separate service
manual must be observed.
