Acute Poisoning

A type of poisoning where symptoms develop quickly and severely.

Chronic Poisoning

A type of poisoning that develops gradually over time, often with repeated exposure to harmful substances.

Temporary Poisoning

A type of poisoning that can temporarily harm the body, but the effects usually disappear over time.

Permanent Poisoning

A type of poisoning that can permanently damage the body, with lasting health consequences.

Safe Current Limits (GOST 12.1.038-82)

According to GOST 12.1.038-82, the maximum safe current that can flow through the human body for more than 1 second is 6 mA for direct current and 15 mA for alternating current.

AC vs. DC Danger

Alternating current (AC) is more dangerous than direct current (DC) at the same strength. This means the permissible limit for AC is lower than for DC.

High Voltage Rescue

If the voltage exceeds 1000 V, use a bar with insulating pliers to move the victim, not bare hands. Rubber gloves are not suitable for high voltages.

Step Voltage Danger

If a wire is on the ground, be aware of step voltage - a potential difference between two points on the ground. This can cause a shock if you stand on one point and touch another.

Single Wire Shock

If a victim is touching a single wire, disconnecting all power sources is the most effective way to prevent further danger.

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.
