The general industry silica standard has the same exposure limit as the construction rule and none of its shortcuts. There is no Table 1 to follow, so exposure assessment is not optional. This guide covers which rule governs your work, the two limits, the written exposure control plan and the medical surveillance clock.

OSHA runs two lead standards with the same exposure limit and very different machinery. Construction presumes exposure from the task itself before anyone samples the air; general industry does not. And the blood-lead level that forces a worker off the job differs between them. This guide sets both ladders out side by side.

OSHA 29 CFR 1910.1030 covers every employee with reasonably anticipated contact with blood or other infectious materials, and it reaches well beyond healthcare. This guide sets out the eight duties the standard creates, who actually counts as exposed, the hepatitis B vaccine clock, and the two very different record retention periods.

Every control in the OSHA construction asbestos standard scales off which of four work classes the job falls into, and misclassifying it is the most expensive mistake available. This guide sets out what separates Class I from Class II, III and IV, what each class triggers, and the two exposure limits that apply throughout.

Every 29 CFR 1910 and 1926 section carrying a practical safety duty, indexed with its official CFR title and a plain-English summary written from the regulation itself. Includes the general industry versus construction crosswalk and the incorporation-by-reference table showing which ANSI and ASTM editions OSHA actually enforces.

OSHA sets safety sign rules in two separate places, and the ANSI editions it incorporates run two to three revisions behind what vendors sell as current. This guide decodes the three sign classes at 1910.145(c), the specified colors, accident prevention tags, and the construction table at 1926.200, plus exit and aisle marking duties.

Every OSHA extension cord requirement with its exact citation: the three-wire hard-usage rule of 1926.405(a)(2)(ii)(J), GFCI protection vs the assured equipment grounding conductor program, the splice and repair restrictions, strain relief, and routing. Closes with the daily two-minute inspection routine that satisfies all of them.

OSHA 29 CFR 1910.151 requires adequate first aid supplies in every workplace without a nearby medical facility. ANSI/ISEA Z308.1-2021 defines Class A and Class B kit contents.

NIOSH vs. OSHA Explained (2026 Guide): NIOSH (National Institute for Occupational Safety and Health) is a research and certification agency within the CDC that approves PPE and sets recommended exposure limits.
