Both PFMCH and PFMD are considered to be non-hazardous by US and EU classifications under normal conditions.
Chemical Hazards:
- Incompatible substances: oxidizing agents, strong acids, strong bases
- Emits toxic fumes (HF) under fire conditions

LIMS Component Table
| ANALYSIS | TABLE | NAME | ABOUT TEXT |
| PFT | SAMPLE | Exp | Exp: expedition number |
| PFT | SAMPLE | Site | Site: site number |
| PFT | SAMPLE | Hole | Hole: hole number |
| PFT | SAMPLE | Core | Core: core number |
| PFT | SAMPLE | Type | Type: type indicates the coring tool used to recover the core (typical types are F, H, R, X). |
| PFT | SAMPLE | Sect | Sect: section number |
| PFT | SAMPLE | A/W | A/W: archive (A) or working (W) section half. |
| PFT | SAMPLE | text_id | Text_ID: automatically generated database identifier for a sample, also carried on the printed labels. This identifier is guaranteed to be unique across all samples. |
| PFT | SAMPLE | sample_number | Sample Number: automatically generated database identifier for a sample. This is the primary key of the SAMPLE table. |
| PFT | SAMPLE | label_id | Label identifier: automatically generated, human readable name for a sample that is printed on labels. This name is not guaranteed unique across all samples. |
| PFT | SAMPLE | sample_name | Sample name: short name that may be specified for a sample. You can use an advanced filter to narrow your search by this parameter. |
| PFT | SAMPLE | x_sample_state | Sample state: Single-character identifier always set to "W" for samples; standards can vary. |
| PFT | SAMPLE | x_project | Project: similar in scope to the expedition number, the difference being that the project is the current cruise, whereas expedition could refer to material/results obtained on previous cruises |
| PFT | SAMPLE | x_capt_loc | Captured location: "captured location," this field is usually null and is unnecessary because any sample captured on the JR has a sample_number ending in 1, and GCR ending in 2 |
| PFT | SAMPLE | location | Location: location that sample was taken; this field is usually null and is unnecessary because any sample captured on the JR has a sample_number ending in 1, and GCR ending in 2 |
| PFT | SAMPLE | x_sampling_tool | Sampling tool: sampling tool used to take the sample (e.g., syringe, spatula) |
| PFT | SAMPLE | changed_by | Changed by: username of account used to make a change to a sample record |
| PFT | SAMPLE | changed_on | Changed on: date/time stamp for change made to a sample record |
| PFT | SAMPLE | sample_type | Sample type: type of sample from a predefined list (e.g., HOLE, CORE, LIQ) |
| PFT | SAMPLE | x_offset | Offset (m): top offset of sample from top of parent sample, expressed in meters. |
| PFT | SAMPLE | x_offset_cm | Offset (cm): top offset of sample from top of parent sample, expressed in centimeters. This is a calculated field (offset, converted to cm) |
| PFT | SAMPLE | x_bottom_offset_cm | Bottom offset (cm): bottom offset of sample from top of parent sample, expressed in centimeters. This is a calculated field (offset + length, converted to cm) |
| PFT | SAMPLE | x_diameter | Diameter (cm): diameter of sample, usually applied only to CORE, SECT, SHLF, and WRND samples; however this field is null on both Exp. 390 and 393, so it is no longer populated by Sample Master |
| PFT | SAMPLE | x_orig_len | Original length (m): field for the original length of a sample; not always (or reliably) populated |
| PFT | SAMPLE | x_length | Length (m): field for the length of a sample [as entered upon creation] |
| PFT | SAMPLE | x_length_cm | Length (cm): field for the length of a sample. This is a calculated field (length, converted to cm). |
| PFT | SAMPLE | status | Status: single-character code for the current status of a sample (e.g., active, canceled) |
| PFT | SAMPLE | old_status | Old status: single-character code for the previous status of a sample; used by the LIME program to restore a canceled sample |
| PFT | SAMPLE | original_sample | Original sample: field tying a sample below the CORE level to its parent HOLE sample |
| PFT | SAMPLE | parent_sample | Parent sample: the sample from which this sample was taken (e.g., for PWDR samples, this might be a SHLF or possibly another PWDR) |
| PFT | SAMPLE | standard | Standard: T/F field to differentiate between samples (standard=F) and QAQC standards (standard=T) |
| PFT | SAMPLE | login_by | Login by: username of account used to create the sample (can be the LIMS itself [e.g., SHLFs created when a SECT is created]) |
| PFT | SAMPLE | login_date | Login date: creation date of the sample |
| PFT | SAMPLE | legacy | Legacy flag: T/F indicator for when a sample is from a previous expedition and is locked/uneditable on this expedition |
| PFT | TEST | test changed_on | TEST changed on: date/time stamp for a change to a test record. |
| PFT | TEST | test status | TEST status: single-character code for the current status of a test (e.g., active, in process, canceled) |
| PFT | TEST | test old_status | TEST old status: single-character code for the previous status of a test; used by the LIME program to restore a canceled test |
| PFT | TEST | test test_number | TEST test number: automatically generated database identifier for a test record. This is the primary key of the TEST table. |
| PFT | TEST | test date_received | TEST date received: date/time stamp for the creation of the test record. |
