Safety Information
Isolate the unit from the electrical supply before changing elements or thermocouples or undertaking
other routine maintenance. Ensure that the heating block is cold.
When reconnecting the heating block, ensure that the electrical connections are sound including
earth supply continuity.
Wear appropriate safety clothing when operating the heating block, including a heat resistant face
shield (tinted for eye protection), gloves and apron.
Load and unload "hot" work with oven tongs.
Do NOT use the heating block in the presence of inflammable or combustible chemicals: fire or
explosion may result. To avoid fire, do not expose combustible materials to heat .
Safety Note Insulation
This heating block contains rockwool fibres in its thermal insulation. The materials used may be in
the form of fibre blanket or felt, vacuum formed board or shapes, mineral wool slab or loose fill fibre.
Normal use of the heating block will not result in any significant level of airborne dust from these
materials; but much higher levels may be encountered in maintenance or repair.
Whilst there is no evidence of any long-term health hazards, we strongly recommend that safety
precautions are taken whenever the materials are handled.
Exposure to dust from fibre which has been used at high temperature may cause respiratory
disease.
When handling fibre always use an approved mask, eye protection, gloves and long sleeved
clothing.
After handling, rinse exposed skin with water and wash work clothing separately.
Before commencing any major repairs we recommend reference to:
- ECFIA Bulletin Number 11
- Guidance Note EH46 (U.K. Health and Safety Executive.)
We will be pleased to provide further information on request. Alternatively our Service Department
will quote any repairs to be carried out at your premises or at our works.
