AG1 Platform requirements

Is there a sufficient working area so work can be performed in a compliant manner

Platform has 2 levels of handrails (approximately 0.5 m & 1.0 m high)

Platform has vertical base boards (approximately 0.25 m high)

Platform has removable chains / self closing gates at the top of ladders

Handrail / obstructions do not hamper insertion of sampling equipment

Depth of Platform = >Stack depth / diameter + wall and port thickness + 1.5m

Sampling Platform Improvement Recommendations (if applicable)

No

Yes

Yes

Yes

No

No

Although the monitoring position doesn't comply with most of the sampling plane validation criteria described in AG1, EN 15259, EN 16911-1, it is the safest & only real means of access practically possible to sample at this sampling point.

EXECUTIVE SUMMARY

Sampling & Analytical Method Deviations

Nozzle size

Due to the high velocities at the sampling point selected in the stack a 4mm nozzle was required to achieve isokinetic monitoring, this does not completely adhere to EN 13284-1.

Sample Line & Sample Point

It was only possible to sample from one representative sampling point for all isokinetic monitoring due to a number of factors i.e. flow being excessively high, swirl being greater than 15° & negative flow experienced throughout sample point locations. This sampling location does not therefore comply with all the requirements of AG1 & IS EN 16911-1.

Velocity & Volumetric Flow Rates

As this sampling location shows high levels of turbulence throughout the results from the standard flow traverse are only indicative. In the past, reports detailing the volumetric flow rate according to fan rating have been used to calculate mass emission rates for this stack.

Negative Flow

During instances of negative flow during the traverse a default figure of 0.01 mmH2O was entered into the traverse data spreadsheet.

Flow Traverse

Due to the erratic nature of the flow at the sampling position a 45 point flow traverse was carried out on each line.
