a. the level, type and duration of the exposure and exposure to impulse noise such as impacts and bursts, variations in the vibration level and recurring bursts; b. effects on the health and safety of employees who are particularly exposed to risk; c. insofar as it is possible, any effects on the health and safety of employees as a result of the combined effect of noise and chemical substances and noise and vibrations at work; d. how the noise affects the possibility of recognising warning signals or other sounds that must be audible in order to reduce the risk of an accident; e. indirect effects on the employees’ health and safety due to interactions between vibrations and the work site or the work equipment; f. action values and limit values for daily exposure to vibrations; see Chapters 2 and 3 of the Regulations concerning Action and Limit Values; g. the manufacturers’ information about the noise and vibration level of the work equipment; h. whether alternative work equipment exists that generates less noise and exposure to vibrations; i. exposure to noise and whole-body vibrations other than during ordinary working hours for which the employer is responsible; j. insofar as it is possible, relevant information from medical examinations and other published information; k. increased health risk because of the combined effect of vibrations and other factors in the workplace; and l. availability of hearing protection that provides sufficient attenuation.
