## Abstract

A removable safety barrier for a construction site pit, in which piles support the sides of the pit, and having a plurality of upright barrier posts at spaced intervals, supported on the piles, the barrier posts extending below grade level around the edge of the construction pit and also above grade level; a plurality of retention panels, shaped to fit between adjacent posts; personal barrier supports secured to the barrier posts above grade level; and personal barrier members supported in the supports, extending substantially transversely between the upright barrier posts, and the retention panels being located below grade level extending between the barrier posts.

## Claims

### Claim 1

A removable safety barrier for a construction site pit, in which piles support the sides of the pit, and comprising;
a plurality of upright barrier posts; at spaced intervals, supported on said piles, said barrier posts extending below grade level around the edge of a construction pit and also above grade level;
a plurality of retention panels, shaped to fit between adjacent said posts;
personal barrier supports secured to said barrier posts above grade level; and,
personal barrier members supported in said supports, extending substantially transversely between said upright barrier posts, and said retention panels being located below grade level extending between said barrier posts.

### Claim 2 (depends on 1)

A removable safety barrier as claimed in claim 1 including a transverse grade level metal beam, extending transversely between adjacent piles at grade level, and a below grade beam extending between said piles below grade level.

### Claim 3 (depends on 2)

A removable safety barrier as claimed in claim 2, wherein said transverse grade level beam provides support around said construction pit, at grade level for the barrier posts.

### Claim 4 (depends on 3)

A removable safety barrier as claimed in claim 3 wherein the barrier posts are connected by fastening clips attachable to the transverse grade level beam, so as to secure the barrier posts to the transverse beam, and hold the entire barrier in position.

### Claim 5 (depends on 2)

A removable safety barrier as claimed in claim 2 wherein the barrier posts are dimensioned to inter-fit with the below grade beam.

### Claim 6 (depends on 2)

A removable safety barrier as claimed in claim 2 wherein the retention panels are supported in rectangular panel frames shaped to inter-fit with the below grade beam.

### Claim 7 (depends on 1)

A removable safety barrier as claimed in claim 1 wherein the barrier posts are formed of hollow rectangular tubular members, and including panel support brackets provided on such posts, to support the retention panels.

### Claim 8 (depends on 1)

A removable safety barrier as claimed in claim 1, wherein retention panels extend partially upwardly above grade level, for additional security.

### Claim 9 (depends on 1)

A removable safety barrier as claimed in claim 1 wherein the grade level beam is L-shaped defining a horizontal portion for welding, to each pile.

### Claim 10 (depends on 1)

A removable safety barrier as claimed in claim 1 wherein the below grade beam is a U-shaped channel.

### Claim 11 (depends on 1)

A removable safety barrier as claimed in claim 1 including flanges on the clips and sleeves on the posts receiving the flanges.

### Claim 12 (depends on 1)

A removable safety barrier as claimed in claim 1 including lips on the clips shaped to inter-fit with the transverse grade level beams.

### Claim 13

A method of erecting a removable safety barrier around a construction site excavation, and comprising this step of securing a transverse grade level beam, a below grade beam to the upright piles around the excavation, attaching barrier posts to the grade level beam at intervals, placing retention panels between adjacent barrier posts, and installing personal barrier rails to portions of the barrier posts extending above grade level.

### Claim 14 (depends on 13)

The method as claimed in claim 13, including the step of attaching the barrier posts to the transverse grade level beam by a series of clips, said clips being dis-engagable, when the safety barrier is no longer required and fitting lower ends of said posts on said below grade beam.
