At the fan-tip speeds required for economical performance, a large amount of noise is produced. The predominant source of noise is vortex shedding at the traihug edge of the fan blade. Noise control of aircooled exchangers is required oy the Occupational Safety and Health... 

Toxic hazards may be caused by chemical means, radiation, and noise. Routes of exposure are (1) eye contact, (2) inhalation, (3) ingestion, (4) skin contact, and (5) ears (noise). An Industrial Hygiene Guide (IHG) is based on exposures for an 8-h day, 40-h week, and is not to be used as a guide in the control of health hazards. It is not to be used as a fine hne between safe and dangerous conditions. 

Whilst the causative agent(s) have not been established it is thought to be multifunctional and possibilities include physical factors (humidity, temperature, lighting), static electricity, electromagnetic radiation, air ion concentrations, fungi, noise, psychological stress, and chemicals. Chemicals which are not those involved in the normal work processes can become trapped within the building, albeit at concentrations below those known to cause ill-health effects, if ...

Not all existing procedures or program elements of the overall health and safety program need to be incorporated into the HASP. For example, if noise is a hazard, the plan does not have to cite the entire hearing conservation program. Procedures already established elsewhere may be referenced, as applicable. In another example, if a confined-space-entry procedure is required, the HASP could reference the particular procedure which is part of the overall program. The next step would be to identify confined spaces at the worksite where the procedure applies, and then provide appropriate implementation procedures (e.g., conditions to be monitored, evaluation of the space, issuance of an entry permit). If special operational procedures apply to the worksite, they can be attached to the HASP using an appendix. 

Congress passed the Occupational and Safety Health Act to ensure worker and workplace safety. Their goal was to make sure employers provide their workers a place of employment free from recognized hazards to safety and health, such as exposure to toxic chemicals, excessive noise levels, mechanical dangers, heat or cold stress, or unsanitary conditions. In order to establish standards for workplace health and safety, the Act also created the National Institute for Occupational Safety and Health (NIOSH) as the research institution for the Occupational Safety and Health Administration (OSHA). OSHA is a division of the U.S. Department of Labor which oversees the administration of the Act and enforces Federal standards in all 50 states. 

Ventilation noise and the annoyance effects which may result have been a recurring question in recent years for researchers, occupational health services, and various aurhorities. In spite of this, there are still major shortcomings in our knowledge about the links between human effects and exposure to ventilation noise. Current regulations and recommendations are thus based on uncertain principles in certain respects. 

The main purpose for the heating and air conditioning of work spaces is to provide an environment that is acceptable and does not impair the health and performance of the occupants. During production processes and in the external environment it may be necessary to work in unacceptable conditions for a limited time period. However, it must be ensured that these conditions do not impair the health of the employees. Light, noise, air quality, and the thermal environment are all factors that influence the acceptability of conditions for and performance of the occupants. This section will only deal with the thermal environment. Several standards dealing with methods for the evaluation of the thermal environment have been published by international standard organizations such as ISO and CEN. 

Provides scientific and technical support for the Federal Environment Ministry, especially with the preparation of legal and administrative regulations in the fields of air quality control, noise abatement, waste management, water resources management, soil conservation, environmental chemicals, and health-related environmental issues. 

Occupational Safety and Health Administration regulations as they relate to (a) safety of design related to injury to personnel (includes such matters as latest vessel design [53], noise level from operating equipment, etc., [20, 21, 22, 23, 24, 25, 26, 27, 28]. (b) safety of the plant layout emdronment which might influence the safety of the plant facilities. 

Noise can constitute a danger to health, and therefore adequate precautions must be taken to protect personnel who are required to be in such an environment. The Health and Safety at Work, etc. Act 1974 has the power to control noise emissions, but the subject is complex. If it is anticipated that noise will exceed acceptable levels then... 

Noise levels between 85 and 120 dB(A) affect the hearing of exposed workers on a dose-related basis. The Leq of the noise is calculated and compared to the criterion currently employed. Under Section 2 of the Health and Safety at... 

Work, etc. Act 1974 an employer has to take all steps, as far as is reasonably practicable, to ensure the health, safety and welfare of his workers. Permissible noise levels are defined by codes of practice, and the figure permitted for employee exposure is 90dB(A) 8-hour Leq. 

The nurse withholdsthe drug and notifiesthe primary health care provider if any one or more vital signs significantly varies from the database, if the respiratory rate is 10/min or below, or if the patient appearslethargic. In addition, it is important to determine if there are any factors (eg, noise, lights pain, discomfort) that would interfere with steep and whether these maybe controlled or eliminated. 

In the U.S., there are local, state, and federal laws regulating health, safety, and the environment. The laws that address the area of pollution control also cover health and safety, toxic substances, noise, transportation, and building site approval. 

Employees must receive health sirveillance for certain work (eg work with flour, lead, chrome, asbestos, noise, isocyanates and some chemicals.

Excessive noise is a hazard to health and safety. Long exposure to high noise levels can cause permanent damage to hearing. At lower levels, noise is a distraction and causes fatigue.
