A. 
The Board of Supervisors desires to provide standards for the operation of industrial uses within the Township in order to protect the health, safety and welfare of Township residents, workers at such establishments, and visitors to the Township. Public health and safety shall be maintained through control of noise, vibrations, dust and particulate emissions, sulfur oxides, smoke, odor, toxic matter, detonable materials, fire hazards, glare, heat, radioactive radiation, liquid or solid wastes, and electromagnetic radiation. These items can cause a serious danger to the public health and safety if they are not properly handled and limited. For example, excessive noise has been demonstrated to cause hearing loss, and air pollution has been proven to exacerbate respiratory difficulties. The dangers of fire are well known, and the control of substances which create a risk of fire is necessary.
B. 
The Board of Supervisors also seeks to protect the public health and safety by imposing traffic and access control and landscaping and screening requirements. Traffic and access controls will lessen the possibility of vehicular accidents. Landscaping and screening will provide a barrier to the use and discourage trespassing. The limitation of outdoor storage serves a similar purpose.
C. 
The Board of Supervisors also seeks to protect the public through the requirement of a plan of access in the event of emergency conditions. This will allow police, firefighters and rescue personnel to gain access to the premises in an efficient and safe manner in times of emergency.
A.
