7.4. the chemicals and chemical products;
11.10. the potential crash risks associated with chemicals and chemical products and their physical-chemical properties: If a company is off. binding regulations for industrial accident risk assessment and risk reduction measures, then, using the procedure defined there, also take account of the requirements of this regulation;
11.10.2. If a company is not bound by the laws on industrial accident risk assessment and risk reduction measures, disaster risk reduction measures is determined by these rules;
11.11. other risk assessment (e.g. new chemical substances risk assessment or emergency risk assessment) results. 12. the Risk shall be assessed on a regular basis, once a year, as well as in cases where: 12.1. significant change in the work environment (for example, product composition, mineral or change of raw materials);
12.2. the introduction of new activities or transformed in the manufacturing process (for example, equipment, technological and control process);
12.3. the work environment inspection results indicate possible chemical exposure risks to workers, the measurements that exceeded the chemical occupational exposure limit values (OELS) or found in the process, equipment or techniques failures;
12.4. the emergency situation that caused or contributed to the accident, fire, explosion or dangerous chemicals or hazardous chemical products;
12.5. in case the approved acute arodsaindēšan or chemical risk factor-induced occupational disease;
12.6. received new information on the chemicals or chemical product safety for health of employees, information about the possibility of fire or explosion, as well as hazardous chemicals or hazardous chemical product spills. 13.12 of these rules in the cases referred to in paragraph prior to the assignment employee, the employer shall assess the risks of change and take the necessary preventive measures. 14. evaluate the risks, even if you perform maintenance and other actions that endanger the health and safety of employees and the workers likely to be exposed to the rule referred to in paragraph 2, the chemicals and chemical products. 15. The employer shall ensure that the work environment in the air regularly determine the concentration of chemical substances and compared to occupational exposure limit values (OELS) and under the economic and technical feasibility of occupational exposure measures the actual value. Exposure to the chemical substances in the air of the working environment and the employer assessed according to these rules the methodology laid down in annex 4. 16. If the inhalation of chemicals and chemical products, the exposure assessment is in compliance with the applicable standards, it is considered that the requirements laid down in these provisions respired chemicals and chemical products exposure assessment work is respected.
17. the measurement of the concentration of the chemical is determined according to the recurrence of chemical exposure index, obtained by dividing the concentration of the chemical (occupational exposure) of the working environment in the air with occupational exposure limit values (OELS): EI = C — — —, which AER EI-chemical exposure index; C-chemical concentrations (occupational exposure concentration) of the working environment in the air.


18. If, in determining the concentration of a chemical in one working day or during a production, chemical exposure index is greater than 1 (EI > 1), exposure of the working environment in air is greater than occupational exposure limit values (OELS). This creates a risk to the safety and health of the worker and the employer should immediately take steps for prevention. 19. If, in determining the concentration of a chemical in one working day or during a production, chemical exposure index is equal to or less than 0.1 (EI ≤ 0,1), chemical exposure in the work environment in the air is equal to 1/10 part of the occupational exposure limit values (OELS) or lower. If it can be shown that these conditions work environment characterized by long-term, periodic measurements may be omitted. 20. the next periodic time intervals for measurement is determined according to the results obtained in previous measurements. The maximum time interval to the next: the periodic measurements is 20.1.64 weeks, if previous measurements EI ≤ 0.25 (occupational exposure concentration is less than 1/4 part of the occupational exposure limit values (OELS));
20.2.32 weeks if previous measurements EI ≤ 0.5 0.25 < (trade expor concentration of zīcij is between 1/4 and half occupational exposure limit values (OELS));
20.3.16 weeks if previous measurements EI ≤ 0.5 < 1 (trade expor concentration zīcij range between half occupational exposure limit values (OELS) to occupational exposure limits (OELS)). 21. The measurements shall be carried out during the work process (typical working conditions). A change in working conditions or potential risks and increase the concentration of chemicals carried out additional measurements. 22. If the work environment in the air quick exposure to chemical substances control alarm shall be provided in the report on occupational exposure limits (OELS).
23. where workers are exposed to more than one chemicals or chemical product (simultaneously or gradually), the risk shall be assessed in the light of all the work used in the chemicals and chemical products and total exposure of between and its impact on the safety and health of workers: 23.1. If the work environment in the air at the same time is more dangerous chemicals with the opposite (antagonisk) the effects of occupational exposure limit values (OELS) remain the same as the If each substance would act individually; 23.2. If the work environment in the air at the same time is more dangerous chemicals with a similar action, (synergic) total exposure to these substances effect is calculated using the following formula:, where C1; C2; CN-concentrations in the air of the working environment (mg/m ³); AER1; AER2; AERn-substances occupational exposure limit values (mg/m ³). Exposure concentrations of substances in relation to the AER (exposure index of EI) summing up must not exceed 1. If the fraction is 1, it corresponds to the total exposure limits.

24. the employer shall document the results of risk assessment, including the results of the measurements required for the risk assessment and the measures taken in the chemicals and chemical products for the elimination or reduction of risks. This documentation is kept for not less than two years. 25. the employer allows employees, their agents and representatives of employees to become familiar with risk assessment and measurement of results, as well as chemicals and chemical products, the effects on the safety and health of employees. 26.
