IS 12081 Part 1: Identification of Asbestos Dust Exposure Areas

Key Points from IS 12081 & IS 11451-1986

• Exposure Limits (from IS 11451-1986):

  • Action Level: Threshold where control measures begin.
  • Permissible Exposure Limit (PEL): Maximum allowable airborne asbestos dust concentration.

• Signage Requirements (IS 12081 Part 1):

  • Above Action Level but below PEL: Use Fig. 1 pictorial warning sign.
  • Above PEL: Use Fig. 2 pictorial warning sign and notice.

Summary Table

Notes:

• Action Level and PEL values are defined in IS 11451-1986 (typically in fibers/cm³).
• Warning signs must be clearly visible at workplaces, on packages, and asbestos products.
• These signs serve as precautionary notices to minimize health risks.

For exact figures and pictorials, refer to IS 12081 Part 1 Figs. 1 & 2 and IS 11451-1986 exposure limits.

IS 12081 Part 1 specifies warning signs for asbestos dust exposure:

Key Points:

• Action Level: Dust concentration above this but below the permissible exposure limit (PEL).
• Permissible Exposure Limit (PEL): Maximum allowed dust concentration (see IS 11451-1986).

Warning Sign Requirements:

• Clause 3.2:
  • Use Fig. 1 pictorial warning sign and notice when dust concentration is > Action Level but < PEL.
• Clause 3.3:
  • Use Fig. 2 pictorial warning sign and notice when dust concentration exceeds PEL.

Summary Table:

Additional Notes:

• These signs must be displayed at workplaces handling asbestos, on packages, and products.
• Purpose: To caution workers about health hazards due to asbestos dust.

If you need the exact pictorial signs (Fig. 1 & Fig. 2), refer to IS 12081 Part 1, which standardizes these visuals for clarity and compliance.

  Minimum size = 300 mm x 450 mm

• Fig. 2 Sign (Asbestos dust above permissible exposure limit):
  Minimum size = 300 mm x 600 mm

Lettering and Color Notes:

• "ASBESTOS IN USE" — Black letters
• "OBSERVE SAFETY RULES" — White letters
• Letter size and spacing should be proportional to sign size but not less than minimum dimensions.

Additional:

• Signs can be scaled larger maintaining proportions.
• Pictorial elements and text spacing must be consistent with the example signs.
