TILT-UP WALL PANEL SAFETY
2
AGENDA

• INTRODUCTION TO TILT PANEL WALLS AND WHY SAFETY
  IS A CONCERN
• INJURY STATISTICS
• OSHA REGULATIONS
• RECOMMENDED SAFETY PROCEDURES

3
INTRODUCTION

• TILT PANEL WALLS
• WALLS ARE CAST ON-SITE ON THE FLOOR SLAB AND THEN
  RAISED INTO POSITION

4
INTRODUCTION

• WALLS ARE HELD IN PLACE BY TEMPORARY STEEL TUBE
  BRACING UNTIL STRUCTURAL CONNECTIONS CAN BE MADE

5
INTRODUCTION

• SAFETY CONCERNS ARE RAISED WHEN THERE IS
  INADEQUATE BRACING OR WHEN BRACING IS INSTALLED
  INCORRECTLY

6
INTRODUCTION

• SAFETY IS ALSO AN ISSUE WHEN TEMPORARY BRACING IS
  REMOVED BEFORE ALL STRUCTURAL STEEL, GROUT AND
  POUR BACK STRIPS ARE COMPLETELY INSTALLED

STRUCTURAL STEEL
7
INTRODUCTION

• THERE ARE ALSO SAFETY ISSUES DURING LIFTING OF
  TILT PANEL WALLS
• CRANE CONNECTIONS MUST BE ENGINEERED TO HOLD THE
  WEIGHT OF THE WALL

8
INTRODUCTION

• ONE OF THE MOST COMMON INJURIES FROM INSTALLATION
  OF TILT PANEL WALLS IS FALLING

INJURY STATISTICS

• ACCORDING TO THE US BUREAU OF LABOR STATISTICS
• NON-FATAL INCIDENCES (2006)
• 86,300 ANNUAL EMPLOYMENT IN PRECAST CONCRETE
  CONSTRUCTION
• 8.1 TOTAL RECORDABLE CASES OF INJURY
• 4.3 CASES RESULT IN DAYS AWAY FROM WORK

10
INJURY STATISTICS

• ACCORDING TO THE US BUREAU OF LABOR STATISTICS
• FATAL INCIDENCES (2006)
• 16 TOTAL FATALITIES
• 3 FROM TRANSPORTATION
• 3 FROM CONTACT WITH OBJECTS OR EQUIPMENT
• 10 FROM FALLS

11
OSHA REGULATIONS

• 1926.704 REQUIREMENTS FOR PRECAST CONCRETE
• TILT-UP WALL PANELS SHALL BE ADEQUATELY SUPPORTED
  TO PREVENT OVERTURNING AND TO PREVENT COLLAPSE
  UNTIL PERMANENT CONNECTIONS ARE COMPLETED

12
OSHA REGULATIONS

• 1926.704 CONTINUED
• LIFTING INSERTS WHICH ARE EMBEDDED OR OTHERWISE
  ATTACHED MUST BE CAPABLE OF SUPPORTING ATLEAST
  TWO TIMES THE MAXIMUM INTENDED LOAD APPLIED TO
  THEM

LIFTING CONNECTIONS
13
OSHA REGULATIONS

• 1926.704 CONTINUED
• LIFTING HARDWARE MUST BE CAPABLE OF SUPPORTING AT
  LEAST FIVE TIMES THE MAXIUMUM INTENDED LOAD
  APPLIED

14
OSHA REGULATIONS

• 1926.704 CONTINUED
• NO EMPLOYEE SHALL BE PERMITTED UNDER PRECAST
  CONCRETE BEING LIFTED OR TILTED INTO POSITION
  EXCEPT THOSE EMPLOYEES REQUIRED FOR THE ERECTION
  OF THOSE MEMBERS

15
SAFETY PROCEDURES

• EMPLOYERS SHALL INSTRUCT EACH EMPLOYEE IN THE
  RECOGNITION AND AVOIDANCE OF UNSAFE CONDITIONS
  AND THE REGULATIONS APPLICABLE TO HIS WORK
  ENVIRONMENT TO CONTROL OR ELIMINATE ANY HAZARD OR
  OTHER EXPOSURE TO INJURY

16
SAFETY PROCEDURES

• EMPLOYERS SHOULD INSTRUCT SUPERVISORS AND WORKERS
  NOT TO REMOVE TEMPORARY BRACES UNTIL ROOF
  STRUCTURE AND/OR COLUMNS ARE IN PLACE TO
  STABILIZE THE BUILDING
• EMPLOYERS SHALL COMPLY WITH ALL OF THE
  REQUIREMENTS FOR PRECAST CONCRETE CONSTRUCTION

17
SAFETY PROCEDURES

• EMPLOYERS SHOULD ENSURE THAT TILT-UP PANELS ARE
  PROPERLY BRACED TO RESIST WIND AND LATERAL FORCES
• EMPLOYERS SHALL USE ONLY CERTIFIED WELDERS WHEN
  WELDING STEEL JOISTS TO EMBEDS AND INSERTS ON
  TILT-UP WALL PANELS

18
SUMMARY

• PROPER ADHERENCE TO OSHA REGULATIONS AND ENSURING
  THE IMPLEMENTATION OF SAFETY PROCEDURES WILL HELP
  PREVENT INJURIES AND FATALITIES WHILE WORKING
  WITH TILT-UP WALL PANELS
