Great care is taken to ensure that OSO Dualstream systems are designed and manufactured to meet general
safety requirements when properly used and installed as recommended in this manual.
It is the responsibility of Users and Engineers to ensure that adequate protective clothing and glasses are worn
when working with the OSO Dualstream system.

SEALS AND INSULATION

Insulation and sealing materials are used in the construction of the OSO Dualstream cylinders. Units are sealed
and when used in the manner for which they are intended the insulating and sealing materials do not present any
known hazard. However always observe the following recommendations:-

1.

Avoid inhalation of fibres or dust, wear face mask.

2.

Avoid eye contamination by fibres or dust – wear eye protection.

3.

As far as possible avoid any skin contact with Fibreglass Insulation, Glass Rope, Mineral Wool, Insulation
Pads and Ceramic Fibre.

OTHER MATERIALS

SEALANTS, ADHESIVES AND PAINTS
Sealants, Adhesives and Paints are used in the construction of the OSO Dualstream components. When used in
the manner for which they are intended they do not present any known hazard.

ELECTRIC

All Cylinders have electrical supply of 240v (enough to endanger life) connected to the Immersion Heater. Always
isolate during adjustment, servicing and repair.
