Safety Tools & Calculators
Interactive calculators and tools to help safety professionals make data-driven decisions and ensure workplace safety.
These tools are for general informational use only and do not replace site-specific review by qualified safety professionals. See our Terms of Service for details.
Available Tools
TRIR Calculator (Total Recordable Incident Rate)
Calculate key OSHA safety performance indicators like Total Recordable Incident Rate (TRIR) and DART rate. Understand your incident rates for compliance reporting and safety program evaluation.
Open ToolFall Protection Calculator
Determine OSHA-compliant fall clearance distances for personal fall arrest systems (PFAS). Ensure adequate space below anchor points for safe work at heights, considering lanyard length and deceleration.
Open ToolHeat Stress Calculator
Estimate Wet Bulb Globe Temperature (WBGT) to assess heat stress risks. Get recommended work/rest schedules based on ACGIH/NIOSH guidelines to prevent heat exhaustion and heat stroke.
Open ToolNoise Exposure Calculator
Evaluate workplace noise exposure levels (TWA and Dose %) based on OSHA 29 CFR 1910.95. Determine if hearing protection or a hearing conservation program is required.
Open ToolCrane Swing Radius Hazard Tool
Calculate crane swing radius and required hazard zone boundaries for mobile and tower cranes. Essential for lift planning, preventing struck-by incidents, and OSHA 1926.1424 compliance.
Open ToolExcavation & Trenching Calculator
Determine OSHA-compliant sloping, benching, or shoring requirements based on soil type and excavation depth (29 CFR 1926 Subpart P). Calculate trench width and prevent cave-ins.
Open ToolPre-Task Plan (PTP) Form
Complete a daily Pre-Task Plan (PTP) to proactively identify task-specific hazards, coordinate with nearby trades, and confirm safety controls before work starts. Generate a PDF for documentation.
Open ToolJob Hazard Analysis (JHA) Form
Conduct a systematic Job Hazard Analysis (JHA) by breaking down tasks, identifying potential hazards, assessing risk (likelihood/severity), and implementing controls using the hierarchy. Generate a PDF record.
Open ToolNIOSH Lifting Equation Calculator
Assess the risk of injury from manual lifting tasks based on the NIOSH Revised Lifting Equation. Determine a Recommended Weight Limit (RWL) for a specific lift, flagging tasks that may lead to lower back injuries.
Open ToolArc Flash Calculator
Estimate the incident energy released during an arc flash event to determine the Arc Flash Boundary (AFB) and required level of arc-rated Personal Protective Equipment (PPE) according to NFPA 70E standards.
Open ToolConfined Space Ventilation Calculator
Determine the time required to properly ventilate a confined space before entry. Calculate how many air exchanges are needed and how long a fan must run to achieve a safe atmosphere for OSHA compliance.
Open ToolRisk Assessment Matrix Tool
Perform qualitative risk assessments using a customizable 5x5 matrix to assign likelihood and severity values, automatically calculate risk scores, and prioritize workplace hazards.
Open ToolLadder Safety Calculator
Ensure proper setup angle for extension ladders based on the 4-to-1 rule. Confirm correct base distance from the wall, minimum ladder length, and maximum working heights to prevent falls.
Open ToolOSHA Minimum Approach Distance (MAD) Calculator
Calculate OSHA-required minimum approach distances for work near energized high-voltage transmission lines per 29 CFR 1910.269 Table R-3 and 1926.960 Table V-2. Includes transient overvoltage factor, altitude correction, and phase-to-phase computations.
