General Information

2.1.3 Confined space precautions

Important Note: The following information is provided to guide users of Sigma SD900 Portable Samplers on the dangers and risks associated with entry into confined spaces.

On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required Confined Spaces, became law. This new standard directly affects more than 250,000 industrial sites in the U.S.A. and was created to protect the health and safety of workers in confined spaces.

Definition of a confined space

A confined space is any location or enclosure that presents or has the immediate potential to present one or more of the following conditions:

•An atmosphere with less than 19.5% or greater than 23.5% oxygen and/or more than 10 ppm Hydrogen Sulfide (H2S).

•An atmosphere that may be flammable or explosive due to gases, vapors, mists, dusts or fibers.

•Toxic materials which upon contact or inhalation, could result in injury, impairment of health or death.

Confined spaces are not designed for human occupancy. They have restricted entry and contain known or potential hazards. Examples of confined spaces include manholes, stacks, pipes, vats, switch vaults, and other similar locations.

Standard safety procedures must always be followed prior to entry into confined spaces and/or locations where hazardous gases, vapors, mists, dusts or fibers may be present. Before entering any confined space check with your employer for procedures related to confined space entry.

General Information

2.2 Sampler overview

DANGER

This sampler is designed for collection of aqueous samples only. Non-aqueous samples may damage the equipment and could result in fire and chemical hazards.

The SD900 sampler automatically collects and preserves liquid samples. The sampler is suitable for collection of conventional and toxic pollutants and suspended solids.

2.2.1 Sampler components

The sampler consists of three main sections (Figure 3). The center section contains the controller. Use the controller to program the sampler and for manual operation. The controller contains the following components:

•Pump—operates in the forward or reverse direction to collect a sample, rinse and purge the intake tube.

•Liquid sensor—allows the sampler to dispense accurate sample volumes into the sample bottle(s). Can be calibrated to specific sample conditions in the field.

•Cable connectors—for power, flow meter or communication.

•Desiccant—absorbs internal moisture in the controller and prevents corrosion.

3.2 Installation guidelines

WARNING

Explosion hazard. This product is not designed for hazardous locations where combustible environments may exist.

Refer to the following guidelines and Figure 6 when evaluating site location.

•If the site is located in a confined space such as a manhole, refer to section 2.1.3 on page 12 for safety information.

•Make sure that the site has a level surface or a place to hang the suspension harness, support bracket or spanner bar (Figure 6).

17

Installation

•

•

•

•

Make sure that the temperature at the site is within the operating temperature range that is specified for the sampler.

Make sure that the intake tube is as short as possible.

Maximize the vertical slope of the intake tube from the sampler to the sample source so that the tube drains completely. This prevents cross-contamination of samples and freezing the tube.

Note: See Specifications on page 5 for limitations on transport velocity and maximum vertical lift.

Note: If site conditions do not permit the intake tube to have a downward slope, or if the line is pressurized, disable the liquid sensor and calibrate the sample volume (section 4.8.2 on page 46).

Install the strainer in the middle of the sample stream (not near the surface or bottom) to make sure that a representative sample is collected.

Installation

3.2.1 Manhole installation

WARNING

Explosion hazard. This product is not designed for hazardous locations where combustible environments may exist.

Installation in a manhole requires suspending the sampler above the sample water. Refer to section 2.1.3 on page 12 for safety information in confined spaces.

Prerequisites:

Use the following hardware to mount the sampler in a manhole.

•Spanner bar or support bracket. A spanner bar is placed inside the manhole and is supported by pressure against the walls. A support bracket has the same width as the manhole cover and is placed directly under the cover for support.

•Suspension harness

Note: See Accessories on page 70 for ordering information.

3.3 Sampler base preparation

CAUTION

Biological sample hazard. Follow safe handling protocols during contact with sample bottles and sampler components. Disconnect the sampler from power to disable the pump before handling.

The sampler is set up at the factory with a single bottle or multiple bottle configuration. To change the bottle configuration:

•Use Figure 2 on page 9 to determine the components that are required for the selected configuration.

•Install the full bottle shut-off device (section 3.3.2.1 on page 20) or distributor assembly (section 3.3.3.5 on page 26).

3.3.1 Clean the sample bottles

Clean the sample bottles and caps using a brush and water with a mild detergent before setting up the sampler. Rinse the containers with fresh water followed by a distilled water rinse. Glass bottles may also be autoclaved.

3.3.2 Single bottle installation

Use a single bottle when one composite sample is needed. A full bottle shut-off signals the controller when to stop sample collection. Refer to Figure 4 on page 16 for a diagram of required components.

Prerequisites:

•One plastic or glass bottle

•Retainer (Cat. No. 2190)

Note: Refer to Figure 2 on page 9 to make sure that the correct sample bottle is used with the correct sampler base and retainer.

Installation procedure:

1.Clean the sample bottle as described in section 3.3.1.

2.If using a 2.5-gallon bottle with the standard base, place a container support (Cat. No. 1502) in the sampler base.

3.Place the sample bottle in the center of the base.

4.Fill the sampler base with ice after the bottle is in place to preserve samples.

Note: The time that it takes the ice to melt varies with the amount of ice used, the external temperature and sample temperature.

5.Place the midsection over the base, making sure that the full bottle shut-off is inside the neck of the bottle.

6.Program the sampler and install in the field.

3.3.2.1 Full bottle shut-off installation

The full bottle shut-off is typically installed at the factory and signals the controller when the bottle is full. Complete the following steps to replace or install a new full bottle shut-off.

Prerequisites:

•Full bottle shut-off device

Installation procedure:

1.Slide the slot in the full bottle shut-off base plate under the retainer pin inside the center section (Figure 7). Make sure that the tube and cable exit through the openings in the full bottle shut-off assembly.

2.Position the thumbscrew over the threaded hole and hand tighten to hold the device in place.

3.Connect the cable on the full bottle shut-off to the bottom of the controller (Figure 7). Turn to tighten.

4.Connect the free end of the full bottle shut-off tubing to the inside tube fitting (Figure 7).
