Situational problems
Task No.1. At studying of working conditions of drivers of trolley buses it has appeared that they are exposed to influence of the general vibration during all change. At measurement of levels of vibration on a cab floor its following parameters are established:
Compound 2 4 8 16 32 63 125
Frequencies of octava strips, Hz
Levels of values 120 119 116 120 121 118 119
Vibration,
Air temperature on a workplace of the driver during the summer period reaches +33 degrees, humidity of 70 %, speed of movement of air of 0.5 km/s. Duration of concentration of supervision - more than 75 %
High risk for own life and life of other people. Actual duration of the working day – 8-9 hours. Noise level in a cabin - 90 db.
The task: state a hygienic estimation of working conditions of drivers;
Define classes of harm and danger of each production factor;
State the general estimation of harm and danger of the given kind of work;
Recommend improving actions.
Task No.2. On underground mines of Dzhezkazgan the self-propelled technics – drilling units, loading delivery technics, auxiliary mechanisms is widely used. In separate faces punchers and scraper crabs are applied. At studying of working conditions presence of following harmful and dangerous factors is established:
- Noise, vibration (excess MCL on 15 db);
- Danger traumatizing;
- Underground waters because of a face and drift;
- Low light exposure (10 lux);
- Contact of hands with lubricant materials
- Air gassed condition (above maximum concentration limit at 3-10 time);
- The dust maintenance in air of a working zone exceeds maximum concentration limit in 2-5 times (the maintenance of free dioxide of silicon – 60 %);
The task: state a hygienic estimation of working conditions of miners;
Define classes of harm and danger of each production factor;
State the general estimation of harm and danger of the given labor process;
Recommend improving actions;
Define necessary complete set means individual of protection for miners.
Task No.3. One of sources dust forming in mines are drill the explosive works. At dry pneumatic drilling blast hole concentration of a dust in a breath zone fluctuates from 234 to 800 mg/m cubic In dust tests to 90 % of dust particles have diameter 05-5,0 microns. At carrying out of periodic medical inspection of working 2 mines the following is revealed: among workers of mine №1 (the maintenance of a free dioxide of silicon in a dust about 38 %) – 6 cases silicosis, at 60 % of mucous top respiratory ways working irritation, at 25 % - mucous an eye and at 7 % - skin; at miners of mine №2 (the maintenance of a free dioxide of silicon nearby–1 %) – 1 case antracosilicosis, at 49 % - irritation mucous, at 27 % - irritation of mucous eyes, at 2 % skin.
The task:
compare the specified concentration of a dust to maximum concentration limit and say about a role of dispersion of a dust and occurrence of a pathology of respiratory organs;
also compare it to maximum concentration limit;
what tests are necessary for definition of a dust content of air by a weight method;
define a class of harm and danger of labor process
