Construction Safety Requirements

Construction Safety Requirements

Abrasive Grinding


All abrasive wheel bench and stand grinders must be provided with safety guards that cover the spindle ends, nut and flange projections, and are strong enough to withstand the effects of a bursting wheel. An adjustable work rest of rigid construction must be used on floor and bench-mounted grinders, with the work rest kept adjusted to a clearance not to exceed 1/8 inch (0.3175 centimeter) between the work rest and the surface of the wheel.
All abrasive wheels must be closely inspected and ring-tested before mounting to ensure that they are free from cracks or other defects.

Access to Medical and Exposure Records
Each employer must permit employees, their designated representatives, and OSHA direct access to employer-maintained exposure and medical records. The standard limits access only to those employees who are, have been (including former employees), or will be exposed to toxic substances or harmful physical agents. Each employer must preserve and maintain accurate medical and exposure records for each employee. Exposure records and data analyses based on them are to be kept for 30 years. Medical records are to be kept for at least the duration of employment plus 30 years. Background data for exposure records such as laboratory reports and work sheets need to be kept for only 1 year.
Construction Standards.21
Records of employees who have worked for less than 1 year need not be retained after employment, but the employer must provide these records to the employee upon termination of employment. First-aid records of one-time treatment need not be retained for any specified period.
