Industrial microclimate

Effect of cooling microclimate on the body:

At very low air temperatures, heat loss by radiation and convection increases significantly, and heat loss by evaporation decreases.

Heat loss exceeds heat production

Industrial microclimate

Typical reaction to General cooling:

Lowering the skin temperature;

Reduced tactile sensitivity of the skin;

Changes in the functional state

of the CNS:

Narcotic effects of coldWeakening of muscle activity

A sharp decrease in the response to pain

Adynamia and drowsiness

Industrial microclimate

Local cooling contributes to:

The development of colds, this is

due to a reflex decrease in the temperature of the nasopharyngeal mucosa. This phenomenon is taken into account in the hygienic assessment of the temperature regime of residential

and public buildings;

Frostbite of the extremities.

There are known cases of frostbite in the legs of soldiers at temperatures close to 0 degrees in combination with a prolonged forced position in the trenches (circulatory disorders).

Industrial microclimate

Occupational diseases when working in a cooling microclimate:

Myalgia, myositis;

Neuralgias;

Obliterating endarteritis.

Industrial microclimate

Study instrumental methods:

Thermometers;

Psychrometers and hygrometers;

Anemometers,

katathermometer;

Actinometers.

Study physiological methods :

Determination of skin temperature;

Cold test;

Subjective assessment of heat perception;

Industrial microclimate

Prevention in the conditions of a heating microclimate:

Standardization temperatures adjusted for the severity of work;

Rest rooms with cooling panels;

Hydraulic procedures;

Salted water for drinking;

PPE (personal protective equipment): the fabric for workwear should reflect the falling rays

Industrial microclimate

Prevention in a cooling microclimate:

Rest rooms with radiant heating;

Hydraprocedures for heating;

Regulated intra-shift breaks;

Special warm clothing.

INDUSTRIAL POISONS – SUBSTANCES THAT ENTER THE BODY DURING INDUSTRIAL ACTIVITY, HAVE A HARMFUL EFFECT ON IT.

Сlassification of industrial poisons

By chemical composition.

Organic poisons – aliphatic and aromatic compounds, chloride compounds, nitros compounds.

Inorganic poisons – metals, acids, alkalis, and halides.

Сlassification of industrial poisons

On the state of aggregation.
