Roof and wall cladding

- Carbon monoxide: through inhalation, is very toxic, displaces oxygen absorption in the blood and poses a risk of explosion - Paints and varnishes (see organic solvents) - Cement: irritating to the respiratory tract and skin, risk of eye damage, when wet chemical burns due to prolonged contact - Quartz dust: prolonged inhalation can lead to pneumoconiosis Paints, varnishes: possible with organic solvents - Organic solvents: flammable or slightly flammable, can cause brain damage with long-term use, degreases the skin (for example white spirit) - Dishwashing products for dishwashers: irritant, risk of serious eye damage Oxygen concentration under normal conditions: 21% Minimum allowable oxygen concentration: 19% Consequences of deviation from normal oxygen concentration - Higher than 21%: increase fire and explosion hazard - Lower than 19%: lack of oxygen, consequences depending on the percentage: drowsiness, unconsciousness and death Circumstances (oxygen concentration too low) - Lack of ventilation - Corrosion - Other reactions that consume oxygen: e.g. bacteriological and biological reactions, fire - Substances that are released into a room and thereby displace the air and therefore Household products - Unblocking agents: corrosive -

Carpeting

Method -

A risk assessment based on an asbestos inventory must have been carried out Any exclusions in the asbestos inventory do not relate to the location where the work must take place Method for material suspected of asbestos - Before work is carried out at locations where asbestos may be present, an assessment of the risk of exposure to asbestos must be carried out on the basis of an asbestos inventory. - If there is a suspicion that asbestos is present, work must be stopped immediately - Warn the operational manager and the client - The client has a sample taken by an independent laboratory to determine whether it is asbestos -

-

In case of asbestos, remove it in accordance with legal regulations

Organic solvents, cyclic compounds, heavy metals, carbon monoxide, paints and varnishes, cement and quartz dust

Examples -

Organic solvents: often made from petroleum, for example turpentine

- Cyclic compounds, for example benzene, phenol, toluene and xylene - Heavy metals: for example lead, mercury and zinc

Harmful effect -

Organic solvents: through inhalation, short-term headache, long-term brain damage Cyclic compounds: benzene and phenol are toxic, benzene is also carcinogenic

-

-

Heavy metals: very toxic
