Sections

16-6. Activity Hazard Analysis (AHA) Requirements.

Activity Hazard Analyses (AHAs) Development

Develop AHAs as per the specified paragraphs, ensuring documentation of crane operator certifications and qualifications before starting specific activities or tasks.

Boom Assembly and Disassembly

Include boom assembly and disassembly operations in the AHA and identify the associated Control Points (CPs).

Portal, Tower, and Pillar Cranes

Before assembly or disassembly, establish work procedures in the AHA, taking into account site-specific needs, including crane location, foundation design, and clearances.

Hoisting with Hydraulic Excavating Equipment

Prepare a hoisting operation specific AHA, documenting operator qualifications, operational testing, and specific conditions for equipment operation.
Ensure adherence to proper operating procedures, including the use of manufacturer's load rating charts, rigging inspection, and use of tag lines.
Maintain adequate communication and ensure the stability of surfaces beneath the hydraulic excavating equipment.

EM 385-1-1 Paragraph 16-6.

16-6. Activity Hazard Analysis (AHA) Requirements.

Develop AHAs according to paragraphs 1-6 or 2-6, as applicable.  Prepare AHAs for all LHE activities, to include the following:

a.  Prior to the start of a specific activity or task, document the crane operator certifications, qualifications, and designations in the AHA.  Submit the AHA to the USACE supervisor for approval or acceptance by the KO or COR.  (16-6.a)

b.  Boom Assembly and Disassembly.  Include this operation in the AHA and identify the associated CP.  (16-6.b)

c.  Portal, Tower, and Pillar Cranes.  Before the assembly or disassembly commences, establish the work procedures to ensure site-specific needs are considered and prepare an AHA.  The AHA must include the following:  (16-6.c)

(1)  The location of the crane in relation to other tower cranes, adjacent buildings or towers, overhead power and communication lines, and underground utilities.

(2)  Foundation design and construction requirements.

(3)  Identify clearances between the tower, the structure, bracing and wedging requirements, when the tower is erected within a structure.

d.  Hoisting with Hydraulic Excavating Equipment.  Prepare a hoisting operation specific AHA. The AHA must include at least:  (16-6.d)

(1)  Written proof of qualifications of equipment operators, riggers, and others involved in the hoisting operations.

(2)  The specific conditions where other personnel may also operate this equipment, as identified in paragraph 16-3.a.

(3)  Operational testing, as described in paragraph 16-8.gg(5).

(4)  Proper operating procedures according to the equipment manufacturer’s operating manual.

(5)  Proper use and onsite availability of manufacturer's load rating capacity charts.

(6)  Proper use of rigging, including positive latching devices to secure the load and rigging.

(7)  Inspection of rigging.

(8)  Use of tag lines to control the load.

(9)  Adequate communications.

(10)  Establishment of a sufficient swing radius for the equipment, rigging and load.

(11)  Stability of surfaces beneath the hydraulic excavating equipment.
