Study Notes
Labor Laws and Safety Regulations
- Employment Agreements (Under 18): It is permissible to have a full liability agreement with employees under 18.
- Ancillary Facilities: Smoking rooms, restrooms, and showers are considered ancillary facilities. Conference rooms are not.
- Building Height Requirements: Household buildings and built-in structures require a minimum ceiling height of 2.5 meters.
Building Codes and Standards
- Vestibules: Building entrances typically include vestibules for transitional space.
- Shower Room Temperature (Winter): Recommended shower room temperature in winter is 20°C.
- Air Movement in Doorways: Administrative and household premises connected to production facilities require air movement speed of at least 0.5m/s at doorways.
- Dressing Room Temperature (Winter): Dressing rooms for street clothes during winter should maintain a temperature of 20°C.
Workplace Hazards and Safety
- Poisoning: Exposure to harmful substances can cause acute or chronic poisoning.
- Harmful Substance Effects: Exposure to harmful substances can affect people both during work and throughout their lifetime.
- Protective Equipment: Shields, barriers, goggles, and gloves are examples of auxiliary protective equipment.
- Electrical Safety: Electrical installations above 1000V with effectively grounded neutrals are more prone to high fault currents, requiring specific safety measures.
Electrical Safety Procedures
- Maximum Permissible Current: The maximum permissible current for human exposure lasting over 1 second is 6 mA for alternating current (at 50Hz) and 15 mA for direct current.
- Alternating vs. Direct Current: Alternating current (50Hz) has a lower permissible limit for human exposure than direct current according to GOST 12.1.038-82.
- Voltage Exceeding 1000V: Use rubber gloves, and specialized tools (insulating pliers and a stick) when dealing with electrical voltages over 1000V in emergencies.
- Grounding (wire on ground): A wire on the ground poses a risk of step voltage.
- Disconnecting Victim (one wire): Disconnecting the power source(s) is the recommended solution to prevent further danger in the case of a victim touching one wire.
- Preventing Harm (during rescue): Use dielectric material to protect yourself. Do not use bare hands and remove victim's clothing first.
