Safety of lithium batteries
Certain heat meter components can be equipped with a lithium
battery.
This type of battery is classified as hazardous.
VALID TRANSPORT REGULATIONS ARE TO BE ADHERED TO IN EACH
CASE! Inspection documents for the batteries used are available on request.
Handling lithium batteries
• store protected from dampness and moisture
•
do not heat to above 100 °C or throw in fire
• do not short-circuit
• do not open or damage
• do not charge
• do not store within reach of children
In the event of an accident, the following points must be heeded:
In the case of a leak:
- cover with sodium carbonate or an equivalent crystal soda
- make gases and vapours precipitate by spraying with water
- make sure of sufficient ventilation
- avoid any direct contact
In the event of injuries:
- If interior components of the dry element should come into contact with the
eyes, rinse thoroughly with water for 15 minutes.
- In the event of contact with the skin, wash with plenty of water and take off
soiled clothing.
- Move away from the accident spot following inhalation.
- Always consult a doctor.
In the event of a fire:
- Use a Lith-X or Class-D fire extinguisher.
- NEVER USE WATER FOR EXTINGUISHING PURPOSES
- Do not use CO

, halogen fire extinguishers with dry substances or foam
extinguishers.
- Move away from the accident spot following inhalation and ventilate the area.
- Always consult a doctor.
