OSHA 30 PREP: THE APP THAT COULD SAVE YOUR LIFE
Falls are the number one killer in construction. This app has the calculator that shows you if your fall protection will actually protect you.
FALL CLEARANCE CALCULATOR
Before you clip in, know if you will survive the fall.
Enter your setup:
- Lanyard length (6ft standard)
- Deceleration distance (3.5ft for shock absorbers)
- Your height to D-ring (6ft average)
- Safety factor (2ft buffer)
Enter the distance to the lower level.
The app shows you:
GREEN SAFE - You have enough clearance. The system will stop you before you hit.
RED DANGER IMPACT - You do not have enough clearance. You will hit the ground before the system stops you. Do not work at this height.
The animated diagram shows exactly what happens in a fall. See the math. Make the right call.
LADDER ANGLE CALCULATOR
The 4 to 1 rule saves lives. But do you actually measure it?
Enter the working height. The app tells you exactly how far the base should be from the wall. Check your actual setup. Know if it is safe.
Too steep? You will fall backward.
Too shallow? The ladder will slide out.
Get it right every time.
TRENCH SAFETY GUIDE
How deep is the trench? What is the soil type? Do you need shoring?
The app tells you:
- When sloping is required
- What angle for each soil type
- When you need a PE design
- Ladder placement requirements
OSHA violations in excavations are in the top 10 every year. Do not be a statistic.
