13.  HEALTH AND SAFETY STATEMENT 

 

 

Health and Safety Information for the Installer and Commissioning-Service Engineer 

 

Under the Consumer Protection Act 1987 and Section 6 of the Health and Safety at Work Act 1974 we hereby 
provide the following information on substances hazardous to health. 

Product range reference: "UCA"

 

 

13.1  During first firing some smoking may occur, this 

is due to the burning off of protective/lubricating 
oils used during appliance production. Most of 
this will have been removed during the 
production testing process. It is a wise 
precaution to ensure that adequate ventilation 
is provided during the initial firing and 
throughout the commissioning period, this is 
particularly important if the discharge air is to 
blow into a confined space. This smoking does 
not constitute a poison hazard. 

 
13.2 AmbiRad products contain no asbestos; 

 

copper is not employed in gas carrying 
components;  solder which has a melting point 
below 450°C is not used;  paints for corrosion 
protection and decoration are heat cured and 
contain no lead. 

 
13.3 The above appliances meet the Electrical 

Safety requirements of EN60 335 Pt 1 1988. 

 
13.4 Small 

quantities 

of adhesives and sealants 

used in the product are dried and cured and 
present no known hazard. 

 
13.5  Insulation and Seals. 
 

Material:  Alumino - silicon fibre 

 

Description:  Tapes 

 

Known hazards: Some people can suffer 
reddening and itching of the skin. Fibre entry 
into the eyes will cause foreign body irritation. 
Inhalation will cause irritation to the respiratory 
tract. 

 

Precautions: Wear protective gloves when 
handling. 

 

People with a history of skin complaints may be 
susceptible to irritation. 

 

Dust levels are only likely when the material is 
abraded. 

 

In general normal handling and use will not 
present discomfort.  Follow good hygiene  
practices, wash hands before consuming food 
or using the toilet.  

 

First Aid: Medical attention must be sought 
following eye contact or prolonged reddening of 
the skin. 

13.6 Thermostat. 

Material: Illuminating Kerosene. 

 

Description: Sealed phial contains a small 
quantity in liquid form. 

 

Recognition: Colourless liquid, paraffin 
oil/petroleum hydrocarbon odour. 

 

Characteristics: Non-corrosive, flammable with 
no poisonous reference - CH poison Class 3 

 

Precautions: Avoid handling. This product can 
irritate and defat the skin. Prolonged contact 
may cause  dermatitis. Avoid breathing vapour. 
Avoid eye contact.Do not ingest. 

 

First Aid: Skin. Wash thoroughly with soap and 
water. 
Eyes. Rinse immediately with copious amounts 
of clean water. 

 

Ingestion: Seek medical advice. 

 
NOTE:

 If skin irritation persists seek medical 

advice. 

 
13.7 Electrolytic 

Capacitor 

Two types are used by random selection: 

 

Recognition:  
 
1.Plastic enclosure  2.Aluminium enclosure 

 

Material: Contained liquid electrolyte 

 

Known hazards: Electric shock possible if 
charged. 

 
   

Precautions: Discharge to ground/earth. Do not 
incinerate. 

 

First Aid: Treat for electric shock if affected.
